Hydrogen (atomic symbol H) is the first element on the periodic table and the lightest of all the elements. It is composed of a single electron and a single proton. By weight it makes up 90 percent of the universe. This is because it is...
Element facts: Flourine
By: Retha Boswell
Fluorine (atomic symbol F) is a pale yellow, corrosive, and flammable halogen gas. It is atomic number 9, located in period 2 and group 17 of the periodic table. The halogens are salt-forming non-metals, and fluorine is the lightest of these. Fluorine is the most...

Helium is a chemical element, which appears in the periodic table of elements as the second lightest element, following the chemical element hydrogen. Helium is the first noble gas showing in the top left side of the periodic table. Helium is the second most abundant...
Element facts: Helium
By: Patricia Jankowski
Helium is an element that occurs as a gas at standard temperature and pressure. It is an inert gas, which means that it is, for all practical purposes, not chemically reactive. One atom of helium has two protons, two neutrons and two electrons, filling its...
Element facts: Bromine
By: Retha Boswell
Bromine (atomic symbol Br) is a liquid, nonmetal halogen. Halogens are all “salt-formers." Bromine is atomic number 35, period 4 and group 17 on the periodic table. As a liquid, Bromine is reddish-brown, heavy and very dangerous. When in vapor form it is...
Element facts: Cadmium
By: Retha Boswell
Cadmium (atomic symbol Cd) is a very soft metal, similar to zinc. It is atomic number 48, group 12 and period 6, positioned directly under zinc on the periodic table. It is one of the 38 elements in groups 3 through 12 known as transition...
