Section 5-1 History of the Periodic Table.  By 1860, more than 60 elements had been discovered, yet chemists had no way of organizing them or agreeing on basic properties of the element.. Atomic number = Total number of electrons. The group number tells you the amount of valence electrons an element has.. The metals are on the left side of the periodic table. The nonmetals are on the right side of the periodic table. . Jennie L. Borders. Section 8.1 – Chemical Bonds, Lewis Symbols, and the Octet Rule.
