In the periodic table Beryllium is the first element in the second group. The chemical symbol is Be. Beryllium is an Alkaline earth-metal which means that Beryllium is really reactive but not as reactive as the Alkaline metals which is the first group. Beryllium has a melting point of 1287 degrees celsius and a boiling point of 2468 degrees celsius. In 1797 Nicholas Louis Vauquelin founded Beryllium. The density of Beryllium is 1.85. Beryllium is between Lithium and Boron. Beryllium is a shiny,steel gray,and metal that can be used for missiles, high-speed aircraft,spacecraft, and communication satellites. When used as an alloying agent in Beryllium copper beryllium can be used as a spring or a spot-welding electrode and non-sparking tool.
Lithium (Li), the third element on the periodic table, has a soft texture and a silver-white color. This element has an atomic number of three, and is located on the periodic table in the second period of the first group. In addition to being the first alkali metal on the periodic table, lithium is also the lightest metal; its weight is about 6.941 atomic mass units (AMU). Because it is a metal, lithium is mainly used in ionic bonds. Its common compounds include lithium hydride (LiH), lithium nitride (Li3N), lithium carbonate (Li2CO3), lithium hydroxide (LiOH), and lithium fluoride (LiF). Lithium is the thirty-third most abundant element and makes up a very small portion of the Earth’s crust. However, due to its high reactivity, it does not naturally occur in its pure form.
Beryllium Beater is a nuclear reactor worker by day and a fighter of crime at night. Beryllium Beater’s most acclaimed story happened on a bright and sunny day, near the city New Alkaline Earth Metals City. Beryllium was having a splendid day walking to his day job at the nuclear reactor when all of a sudden, it seemed as if the dome surrounding the city had been breached and it wasn’t long until his arch nemesis Oxygen Odor Man would be there! Beryllium chased through the streets of the other Alkaline Earth Metals who were running for safety. Beryllium Beater needed some time to figure out what to do, so he sprinted to the large oven. He did this because his melting point is very high (1278 Celsius) and he wouldn’t be distracted. Beryllium beater ripped open his new steel coat to reveal his superhero costume. It was decorated with grayness to match his own skin color and with a touch of emerald since he’s very close and have similar personalities. He came out into the city with his costume, which had a protective layer of Oxide BeO to protect him from Oxygen Odor Man. He ran to escort people back to their homes before Oxygen came to get them! He met up with his sidekick Cookin’ Copper Man about halfway through the
Molybdenum is a transition metal. It is represented by the symbol Mo. It is a pure metal that is is silverish white in color and very hard, and has one of the highest melting points of all pure elements at 4753 °F. Its boiling point is 8382 °F. Its density is 10280 kg/m3 and its hardness is 5.5.
The periodic table contains many different kinds of elements which are placed accordingly on the table. Potassium is in the alkali metals which is placed in group 1 of the table, alkali metals are among the most active metals. This element was found in 1801 by a man named Humphry Davy. Although the element does not have many uses in pure form as a compound it has many important purposes. Potassium is naturally in the human body if levels become too low or too high then it could cause problems for the individual. Low levels of potassium could cause muscle problems such as cramping and the muscle feeling weak, the person could have a hard time walking or holding onto objects. A serious concern would be the effects on the heart as it causes blood pressure to increase and abnormal heart rhythms.
The Beryllium element, an alkaline earth metal which belongs to group II of the periodic table, was first discovered in 1798 by L.M. Vauquelin. Vauquelin,a French chemist, was doing work with aluminum and noticed a white powder that was nothing like that of aluminum or any of its derivatives. Vauquelin named this mystery powder, gluinium because of its sweet taste was like that of glucose. In 1828, Wohler, a German metallurgist reduced it to its metallic form and renamed it beryllium.(figure 2)
What is Beringia? Beringia, also known as, The Bering Strait, is a massive landmass that the first americans crossed over to get to the Americas during the first Ice Age, about 2.6 million years ago. The time period known as Pleistocene Ice Age is when the first Ice Age happened. Many glaciers covered the sea and lowered the sea level about 300 feet. The land that is now covered by water became dry land. This resulted in the massive landmass that connected the continents of Asia and North America. This land bridge formed a flat, grassy, treeless plain that the first Americans used to migrate to the Americas. When the Earth passed into its climate warming cycle, the glaciers began to melt. The melted water levels rose, and submerged Beringia once again.
Elements are the basic building blocks of matter due to the fact that they are chemically the simplest substances. Whether we can find them in the air or in our gold/silver necklaces, elements are everywhere! One essential element is hydrogen, the first element on the period table (located under Group 1 as an alkaline metal) is composed of a single proton and electron; therefore having an atomic number and atomic mass of 1 and electron configuration of 1s1. In fact, hydrogen is the lightest, simplest and most commonly found chemical element in the universe (it makes up about 90% of the universe by weight). Interestingly enough, the heavier elements on the periodic table were either made from hydrogen or other elements that were made from hydrogen. The most common isotope formed of hydrogen is protium, with 1 proton and no neutrons. Hydrogen can also exist as both positively or negatively charged. The physical form of hydrogen at room temperature is a colorless and odorless gas. Hydrogen gas is extremely flammable and because of this chemical property, it is used as fuel for the main engine of space shuttles. Hydrogen is an important element and has received a lot of recognition throughout history for its usefulness.
Gallium is a metal that was discovered in 1875 by Paul Emile Lecoq De Boisbaudren and is a “byproduct of the manufacture of aluminum” (“Gallium.” Web). Gallium has a low melting point of 29.76°c which is just slightly above room temperature. But even with an unusually low melting temperature, gallium has a very high boiling point of 2204°c. “Gallium expands by 3.1% when it solidifies” (“Gallium.” Avalon). Gallium was an element that was predicted by Dmitri Mendeleev and it “Validated his periodic table of elements” (“Gallium.” Avalon). When in solid form, Gallium has a Silver and reflective appearance.
People arrived in North America around 14,000 BP (BP = Before Present). Evidence for the arrival of Homo sapiens is found throughout the Bering Strait (then Beringia), Siberia, and Alaska. Homo sapiens arrived through Beringia, most likely through the boat, despite the lack of evidence. Homo sapiens are said to have originally rooted in Africa; from Africa, Homo sapiens migrated north into Europe and Asia over the course of 10,000 years and then over to North America followed by South America. Along the time that Homo sapiens were moving into Eurasia, there was also proof of Homo sapiens moving into Australia (Choi, 2014) showing that they had a good idea of marine travel, something that will be important when considering the
In Paul Bereyter,W.G. Sebald uses detailed descriptions of the world around him to distract the reader from Bereyter’s growing depression and seclusion. Like in the story of the boy who cried wolf, Bereyter’s initial suicide attempt numbed people to his later signs of depression and eventual death. His connection to and description of nature draws the reader, and Bereyter himself, into believing in his world of false bliss. This false world comes to an end when Bereyter loses his sight and consequently his connection with nature. After this lost connection, he feels he has no reason to continue living.
Do you like to take pictures in good lighting to get that GLOW? Well taking a picture with good light or simply looking for something in the dark with a source of light was possible with the help of Henry Bessemer. The steel he made is used in wires and we use wire for light so your glowing pictures wouldn't be possible without Henry Bessemer. We all love taking pictures for our Instagram and to have that amazing feed. Without light most of our pictures would be dim and boring.Am I right? Before Bessemer made steel we used cast iron and wrought iron. That material is way to heavy to make wires so that wouldn't help with our lighting issues.We used wrought iron sort of like a heavy substitute for
A hero is a man of courage and ability who is admired for his brave deeds and noble qualities. A hero is a person who does not come along very often in any time period. He is a special person, who is a step above the average person in the way that he handles any situation that may arise.
Hydrogen sulphide has a boiling point of -82 degrees Celsius and a melting point of -60 degrees Celsius. There are 2 hydrogen and 1 sulphide molecule. Simple molecule’s which are covalent have lower melting and boiling points as they do not need too much energy to separate the bonds because they are as polarised as water. In hydrogen sulphide the intermolecular forces are known as Dipole-Dipole forces which are less powerful than hydrogen bonding which is in water therefore water has the strongest bond compared to hydrogen chloride and hydrogen sulphide. Water is more electronegative than hydrogen chloride and hydrogen sulphide because there are more molecules in water which are drawn together however in hydrogen sulphide there are less molecules
The Periodic Table of Elements is commonly used today when studying elements. This table’s history begins in ancient times when Greek scientists first started discovering different elements. Over the years, many different forms of the periodic table have been made which set the basis for the modern table we use today. This table includes over 100 elements and are arranged by groups and periods. Groups being vertical columns and periods being horizontal columns. With all of the research conducted over the years and the organization of this table, it is easy to use when needed.
A man named Sir Henry Bessemer was born on January 19, 1813 in the city of Charlton, Hertfordshire, in England. Bessemer was an engineer and inventor whose process was the first to manufacture steel in an inexpensive way during the year 1856. Eventually, this led to the Bessemer converter. Bessemer was born into a family with mechanical skills, as his father was a typefounder and engineer. In his early years, he showed remarkable skill when dealing with mechanics, as well as having the eye for invention.
