An electron shell is the set of allowed states that share the same principal quantum number, n (the number before the letter in the orbital label), that electrons may occupy. The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. Oxidation states are typically represented by integers which may be positive, zero, or negative. It is the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities.

Titanium can be used in surface condensers. The chemical symbol for Gadolinium is Gd. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ cation. Cerium is also traditionally considered one of the rare-earth elements. The chemical symbol for Beryllium is Be. The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons. It is a soft, silvery-white alkali metal.
