C
Cation-positively charged ion (metal)
Chemical Symbol-One or two letter symbol shown on the periodic table that represents an element
Chemical Symbol-One or two letter symbol shown on the periodic table that represents an element
D
Dot Diagrams (Lewis Dot Diagrams)-Diagrams that use dots to show the number of valance electrons an element has
E

P
Period-horizontal rows on the periodic table
Periodic Table-A system of rows and columns that repeats in a pattern and organizes all known and unknown elements according to atomic number, and other characteristics. The name of the element, chemical symbol, atomic mass, and atomic number are all located on the periodic table.
Protons-Positively charged subatomic particles. Determines what element the atom is
