History of Silicon In 1824, J.J. Berzelius discovered an amazing element thats in so many things today that many people do not even know they're using it. Silicon. Silicon was discovered by Berzelius

There are six main periodic trends: -Electronegativity Trend: chemical property; describing an atoms ability to attract and bind to electrons. -Ionization Energy: the amount of energy required to remove an electron from a neutral atom -Electron affinity trends: ability of an atom to accept an electron -Atomic radius trends: one-half of the distance between the nuclei is the same as the radius of a circle -Melting Point Trends: the amount of energy required to break a bond to change a substance from a solid to a liquid -Metallic Character Trends: the metallic character of an element can be defined as how redly an atom can lose an electron
Periodic Trends
Different Types of Periodic Tables There are many different types of periodic tables. The following three are examples:
The ADOMAH periodic table is based on the electron's quantum numbers
Rota Period- based on valence of the various elements
Left Step Periodic Table- organized elements according to orbital filling

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
Primo Levi’s personal relationship to his profession as a chemist shows that philosophically and psychologically, he is deeply invested in it. His book THe PeriOdic TaBLe shows that his methodology cannot be classified as either purely objective or purely subjective. He fits into the definition of dynamic objectivity given by Evelyn Fox Keller in her book Reflections on Gender and Science.
Just as the title of the chapter suggests, the main focus of Chapter 11 is how elements found on the Periodic Table are not always what they appear. Kean begins this chapter with describing how elements can be unpredictable in some conditions, and uses example from the past to...
Strontium was discovered by Adair Crawford, an Irish chemist, in 1790 while studying the mineral witherite (BaCO3). When he mixed witherite with hydrochloric acid (HCl), he did not get the results he expected. He assumed that his sample of witherite was contaminated with an unknown mineral, a mineral he named strontianite (SrCO3). Strontium was first isolated by Sir Humphry Davy, an English chemist, in 1808 through the electrolysis of a mixture of strontium chloride (SrCl2) and mercuric oxide (HgO). Strontium reacts vigorously with water and quickly tarnishes in air, so it must be stored out of contact with air and water. Due to its extreme reactivity to air, this element always naturally occurs combined with other elements and compounds. Strontium is very
Heavy metal music has developed greatly ever since it was created in the late 1960’s, evolving into large and varied categories of subgenres. It is not uncommon for types of metal to be confused for one another despite their distinct differences. There are hundreds of subgenres, but three of them will be discussed, the bluesy and distorted doom metal, the fast and fantastical power metal, and the ill reputed black metal.
Discovered in 1808 by J.L. Gay-Lussac and L.J. Thenard in Paris, France, and Sir Humphry Davy in London, England, boron is element number five on the Periodic Table of the Elements. The name "boron" comes from the Arabic "buraq" (pronounced borax). The actual element boron is not commonly used, but compounds of boron are very common. These compounds can be found in such household items as detergent. Boron is also used in Pyrex glass, which makes the glass more heat resistant. Boron is also an essential mineral for plants and animals, although it can be toxic in large quantities (Chemsoc 1). Boron has many common uses, but there are also many advantages to using it as and alternative form of fuel.
However, it can also be located in the in the bulk of the silicon both
In 1907, Einstein used Planck’s hypothesis of quantization to explain why the temperature of a solid changed by different amounts if you put the same amount of heat into the material. Since the early 1800’s, the science of spectroscopy had shown that different elements emit and absorb specific colors of light called “spectral lines.” In 1888, Johannes Rydberg derived an equation that described the spectral lines emitted by hydrogen, though nobody could explain why the equation worked. This changed in 1913 when Danish physicist Niel Bohr applied Planck’s hypothesis of quantization to Ernest Rutherford’s 1911 “planetary” model of the atom, which affirmed that electrons orbited the nucleus the same way that planets orbit the sun. Bohr offered an explanation for why electrical attraction does not make the electrons spiral into the nucleus. He said that electrons in atoms can change their energy only by absorbing or emitting quanta. When an electron absorbs a quantum it moves quickly to orbit farther from nucleus. When an electron emits a quantum the electron jumps to a closer
It was discovered by Sir Humphrey Davy in England, in 1807. Sir Davy was able to isolate potassium using electrolysis. Potassium was the first metal isolated by this procedure. Today, it is still not found free in nature. It is obtained by electrolysis of chloride or hydroxide.
As elements get heavier the ratio of neutrons:protons moves away from being 1:1, Bands of instability surround the band of stability showing where the neutron:proton ratios are either to great or too small,
In 1937, technetium-99m was discovered by C. Perrier and E. Segre. It is a radionuclide, and was first discovered as an artificial element that was used to fill space number 43 in the periodic table. 1
Brand was obsessed with finding the Philosopher’s Stone; this stone reputedly could change metals into gold. With his discovery, this made Brand the first known discoverer of an element. In 1669, he isolated human urine and distilled it which resulted in a white and waxy material. Brand named this material phosphorus (light bearer) because it glowed in the dark. This discovery was kept a secret until 1680 when an English chemist Robert Boyle discovered phosphorus independently. Boyle’s definition of this element was simply “a substance that cannot be broken down into a simpler substance by a chemical reaction”. This definition of the element lasted for three centuries until the discovery of subatomic
Report on Ionization Energies INTRODUCTION: The ionization energy of an atom measures how strongly an atom holds its electrons. The ionization energy is the minimum energy required to remove an electron from the ground state of the remote gaseous atom The first ionization energy, I1, is the energy needed to remove the first electron from the atom: i.e. the most loosely held electron!

In chemistry, metals compose a great number of the periodic table elements. Each metal has its own characteristic mass,
