First, let’s look at Periodic Table and Group numbering. 14.1 Hydrogen. The simplest atom, ~90% of all atoms in the universe. The only element whose isotopes are each given a different symbol and name. 1H (or H, protium) = one proton (p+), plus one e-surrounding it. 2H (or D, deuterium) = one p+ and one neutron (n), plus one e-

Si [Ne] 3s23p2, 15. P [Ne] 3s23p3, 16.

The arrangement of the Periodic Table The periodic table also groups elements based on other attributes. Metals are generally found on the left-hand side of the table in groups 1-12 and some in groups 13-16. The periodic table is a tabular arrangement of the chemical elements.
