Next SectionPeriodic Table: Elemental Forms

The Element Symbols of the Periodic Table represent the abbreviated form of an element

Element Symbols

Concept #1: Most element symbols are based on the first letter(s) of the element, but a few are based on their Latin names.

Example #1: Name the halogen with the smallest atomic number.

a) Fluorine, F                 b) Chlorine, Cl                 c) Bromine, Br                 d) Iodine, I                 e) Scandium, Sc  

Practice: Based on the number of protons each element has, which would you expect to be chemically similar?
