Gallium: An Element Found In France

The elements were organized by Dimitri Mendeleév. He organized them by properties (columns), groups (horizontal), and atomic number (the number of protons and electrons). This became known as the Periodic Table. And currently there are 118 elements. He also found gaps in which elements that were yet to be discovered were to go, three of these unknown elements were found and identified in Mendeleév's lifetime. The elements today are used in everything and 75% of the 118 elements are metal.

Silver is an element that is found on the Periodic Table. The element silver is symbolized on the periodic table with the letters Ag. The symbol Ag of silver comes from a latin word for silver which is argentum. Silver on the Periodic Table is found in group 11. Silver has an atomic number of 47. The atomic number determines the chemical properties of an element and is placed on the top of the symbol on the periodic table. The mass number of the element silver is 107. To determine the atomic number you use the number of protons and neutrons in the element. Silver has 60 neutrons which is a subatomic particle found in the nucleus of every

Mercury: The element mercury has the chemical symbol Hg; it is a silver colour and is a liquid at room temperature. Mercury has a high density and surface tension and can easily break up into small droplets. Mercury can dissolve some metals resulting in amalgams, metal alloys of mercury. It is not soluble in water or most other liquids, but will dissolve in lipids (fats and oils). With fluctuations in temperature, mercury expands and contracts evenly with these changes and is classed as a non-combustible liquid. (Mercury characteristics)

chemical element here on our own planet Earth. Though it is a rare, unreactive noble gas,

As previously stated, mercury is number 80 on the periodic table of elements. It is a metal, a transition metal to be exact. It has a symbol of “Hg”, an atomic mass of 200.59, and there are 7 known stable isotopes

Only barely enough Americium has been produced to know a few of its properties. Some of the physical properties that it has are basic properties. It is a shiny silvery-white color and is very radioactive. Americium has few chemical properties. For example, at room temperature Americium is a solid, but it tarnishes slowly in dry air. Its melting point is

Though there are over a hundred different elements, each one is unique in its complexity and properties. Helium has an atomic Number of two, that’s how you can tell it it has two positively charged atoms, or ‘protons’, in

With Bromine being element number 35 on the periodic table, it is also very reactive as it is part of group 17, the Halogens. The Halogens are the most reactive group in the periodic table. Bromine’s atomic mass is 79.904. Bromine also has 2 stable isotopes. Its mass numbers are 79 and 81. Chlorine,

Isotopes are essential to the universe in a chemical and even a social aspect, standing as a variation of an element portrayed as unique. Important questions surround isotopes, how are they distinctive and ultimately what is an isotope? To answer that question, isotopes are a form of an element that differs in the number of neutrons in the nucleus but does not differ in protons of that element. An isotope in particular that contributed to society is Plutonium-238, which is understood to be a radioactive isotope.

The Element: Chlorine General Information We researched the chemical element known as chlorine. Chlorine has an atomic number of 17 and an atomic weight of 35.453. It has a valence number of 3. The element has 3 energy levels. Chlorine exists as a greenish-yellow gas at normal temperatures and pressures.

Gallium is the element number 31. Gallium is the one of the only metal that will be liquid in your hand. Mercury is an liquid metal element number 80 that freezes at -280 degrees fairenheight with liquid nitrogen. Mercury was a popular thing to play with but people realized that they were slowly being poisoned by it.Gallium is not known to be toxic, but it can stain your hand dark brown. cesium is another metal that will literally melt in your hand but without putting it in an ampoule, it will explode and catch on fire. Gallium tends to be the less dangerous type of liquid metal other than explosive cesium to lethal mercury. Gallium melts at a temperatue of 83.4 fairenheight. In order to buy gallium you must first order it then, they must purize

The fourth most abundant and by far one of the most interesting elements, Neon, is definitely unique. The tenth element on the periodic table is known as a noble gas, with the symbol ‘Ne’. This element has a density of 0.0008999 g/cubic meter, a boiling point of -246.08 degrees Celsius, three natural isotopes, an atomic mass of 20.179, and a melting point of -248.59 degrees Celsius. It’s atomic number is ten, and its atomic mass is 20.179.

Today we will be talking about two very important elements, one of them is called Silicon. The other is called germanium. These elements are important because without them, you wouldn’t be able to do most of the things that you consider “fun”. So I would first like to start off talking about Germanium and then finish off by talking about Silicon. So here we go.

My element is Boron. Boron compounds such as borax have been known and used by ancient cultures for thousands of years. Boron was first partially isolated in 1808 by French chemists Joseph L. Gay-Lussac and L. J. Thénard and independently by Sir Humphry Davy in London. Davy first tried to produce Boron by electrolysis of boric acid, but was not satisfied with how the results turned out. In 1909, American chemist Ezekiel Weintraub was able to produce 99% pure Boron, by reducing Boron halides with hydrogen. In 2004, Jiuhua Chen and Vladimir L. Solozhenko produced a new form of Boron, but were not certain of its structure. Boron is a tough element, very hard, and very resistant to heat. In its crystalline form, it is the second hardest element of all the

Germanium weighs 72.61lbs, and the boiling point is 2830 degree Celsius. In addition, germanium has 9 isotopes, and the atomic mass i 72.59. However, “the element germanium is both metals and nonmetals. To be more precise, germanium is a very important element that light and shiny.
