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. This element when becoming an isotope can become radioactive due to its high activity as a metal. In its natural state it is a soft metal and it has a shiny “ wax “ like silver/white color to it, it is so soft that a knife could cut through it without a problem. …show more content…
Such as Potassium Carbonate ( CK2O3 ) has an average mass of 138.206 Da. It’s appearance is a powder that is white in color.

Potassium Nitrate ( KNO3) has an average mass of 101.103 Da with a colorless crystal appearance or in white powder form. It is soluble in water, glycerol, and liquid NH3. It is stable and a strong oxidizer that has a melting point at 334 degrees celsius.Potassium nitrate is found in fertilizers, gunpowder, and in fireworks. Potassium hydrogen carbonate ( KHCO3 ) has an average mass of 100.115 Da and is stable. It also has a white powder or crystal appearance with a melting point at 100 degrees
Together extra-renal factors (insulin, epinephrine, aldosterone) and renal factors maintain a normal potassium plasma concentration in the body. The extra-renal mechanisms are responsible for moving potassium into the intracellular compartment. The renal mechanisms are responsible for chronic maintenance of body potassium content. When these mechanisms are functioning correctly, large intake of potassium has a minor and insignificant effect on the potassium concentration in the plasma. [5&6]
Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted
The only way to decrease concentrations of this isotope is through radioactive decay which would therefore stabilize the isotope. Strontium is also a very small key player in the toothpaste industry. It serves as an ingredient in the toothpaste of Sensodyne, which is used to help those that suffer from sensitive teeth. Besides being used in all these industries, Strontium is also used to refine Zinc and make it free from impurities and other extra stuff. It helps to reduce the impurities that are present from Lead. Lead is such an element that it contains many different elements inside of it, such as Zinc, Bismuth, Antimony, etc. Strontium helps to isolate these elements and make them appear in the pure form. Strontium was also used to create one of the world's first atomic clock. Atomic clocks help keep accurate time, and they are used all over the world in many different fields. It is amazing to see how a small invention can change the world. In conclusion, Strontium is a very fascinating element that has many functions and it also serves many roles in a variety of
Two chemists came upon the discovery and those two are: Sir William Ramsay, who is from Scotland, and Morris M. Travers who is from our homeland. This element was founded on May 30, 1898. The way that those two came upon the element Krypton was that they first found the elements Argon and Helium. From using their common knowledge they figured that there had to be some elements between those two on the periodic table, so they did a ton of experiments and through trials and trials they came up with a couple more elements and one of those elements was Krypton. Next the essay will discuss the shape of Krypton and where it is found.
...ium at its normal state, room temperature-solid metal. It is almost impossible to imagine that people ingest potassium in forms of pills and foods for health benefits.
The % composition by mass of oxygen in Potassium Chlorate was found to be 43.4%.
Magnesium, also known as atomic number 12 was discovered in 1808 by Sir Humphry Davy who was a British Chemist best known for his experiments in electro-chemistry and his invention of a miner's safety lamp (BBC News, 2014). Magnesium is a chemical element with symbol Mg. Magnesium is a light, fairly strong, whitish, silver Alkaline Earth Metal that is the eighth most abundant element in the Earth's Mantle and the fourth most common element on earth, making up 13% of the planet's mass (Winter, 2011). Its atomic weight is 24.305.
The name comes from the Latin word alumen, for the mineral alum. The electron configuration is [Ne] 3s2 3p1. The element looks solid at room temperature and is a classification of other metals. Its crystal structure is cubic. Aluminum is not an element found in nature, it is found in the earth’s crust which is 8.2 percent of it. Aluminum is obtained from rocks called bauxite. It is the most available element. In the beginning, scientist suspected it was in the earth’s crust. There were many chemists who produced aluminum. The very first was Hans Christian Oersted in 1825. Its color is silvery-white with a bluish tint. The element is soft but it becomes strong and hard when combined with other elements. The atomic number of it is 13, which means that the atom has 13 protons therefore 13 electrons. It has 14 neutrons. The atomic weight is 26.98154. The melting point is 660.37 degrees Celsius. The boiling point is 2467 degrees Celsius. As for the atomic structure, the element has three energy levels. The first has 2, the second has 8 and the third has 3.
Calcium and Potassium modifications are specialized individual according to a specific disease, age and inadequate amounts of calcium or potassium higher or lower than normal value.
Radium is the 88th element on the periodic table, its family group is Alkaline Earth Metal. Radium is a chemical element with symbol Ra. Pure radium metal is bright white when freshly prepared, but blackens once it is exposure to air. Radium has been used to produce neutron sources, luminous paints, and medical radioisotopes. Marie Curie is known to be the mother of science, due to Marie several discoveries, Mrs. Curie made up most of the Earth metals in the periodic table. Marie discovered Radium and other key elements, which help us in our daily lives, especially taking x-rays. Marie was also the first person honored with two Nobel Prizes in both physics and chemistry.
Sodium originated from the Arabic word “suda” meaning headache because sodium carbonate was used as a headache remedy. It is also one of the most well-known compounds to ancient people (Newton). It is a component of sodium chloride (NaCl) which is found everywhere in nature (Sodium Lenntech). Sodium is the sixth most abundant element in the Earth’s crust and the second most abundant element dissolved in sea water (Sodium Lenntech). Although sodium is abundant on Earth, it is never found in free nature (The Element). Our bodies need sodium in order to work properly. The body needs sodium to help control the muscles and nerves (Sodium in). The body also uses sodium to control volume and blood pressure. Sodium is a slivery-white metal that always occurs as part of a compound (Newton). It is very easy to cut and when it is cut it changes to a very dull color because it is exposed to oxygen (Sodium Lenntech). Sodium must be stored in a moisture free environment because it is very highly reactive (Element). It has a chemical symbol of Na, and has an atomic mass of 22.99 and a periodic number of three (Bentor). It was founded hundreds of years ago.
periodic table is arguably one of the most important developments in the history of all science. Development of the table spanned over more than 2000 years beginning with the proposal by Aristotle around the year 330 BC that there is limited number of elements (though at the time he referred to them as roots) that make up everything in the universe, though he believed these elements to be simply "water, fire, earth, and air" and made no further contributions to the development and understanding of the table and its properties.
Sodium carbonate also known as washing soda is a white solid and has the chemical formula of Na2CO3. The molar mass of sodium carbonate is 105.9888 g/mol. Sodium carbonate is formed naturally; when sodium is released from igneous rocks and when it is carried away by the rivers it comes in contact with carbon dioxide it will participate out as sodium carbonate. Just to get sodium carbonate to its boiling point is impressive you have to it to a temperature 1,554̊ F and its melting point is 2,912̊
