Element Cube - Example
/ Cars can run on hydrogen and South Carolina is one of the leading states in doing research on the use of hydrogen.
On Earth, hydrogen is never alone. Elemental hydrogen is always diatomic, meaning one hydrogen atom always combines with another hydrogen atom to form a 2-atom molecule with a covalent bond (atoms share electrons in covalent bonds). Elemental hydrogen’s symbol is H2. /
/ Elemental hydrogen freezes at 14K or –59C and it boils at 20K or –253C.
Hydrogen is found in column 1 of the periodic table of elements, but it’s NOT an alkali earth metal even though all the other elements in column 1 are alkali earth metals.
Hydrogen is the most abundant element in the universe and the 3rd most abundant element on earth.

Hydrogen ions:
  • When hydrogen atoms combine with non-metal atoms or negatively charged polyatomic ions, it most often gives away that electron to the metal ion polyatomic ions.
  • In water, these hydrogen compounds become acids, allowing the positively charged hydrogen ion (H+) to flow freely in the water.
  • When a hydrogen atom loses its only electron, it’s no longer an atom, it’s an ion and it has a 1+ charge. The symbol for that hydrogen ion is H+.

  • Since a hydrogen atom only has one electron, if it looses that electron, the only thing left on most hydrogen atoms is a proton. So a positively charged hydrogen atom is often simply called a proton.
  • Note: Positively charged ions are called cations.
  • In rare cases, hydrogen atoms gain an extra electron (giving it 2 electrons). This also is no longer an atom; it’s a negatively charged ion called a hydride. Its symbol is H. Note: Negatively charged ions are called anions.

/ Chemical symbol is H. Atomic number is 1 (1 proton in its nucleus).
Average atomic mass is 1.00794 u. Average atomic mass is the average mass of all the known isotopes of an element.
The orbital notation isH:
1s
Electron configuration: H: 1s1
The hydrogen ion H+ (also referred to as a proton) has an electron configuration of H+: 1s0. /
