Gold is a type of metal on the periodic table

Atomic number, Atomic Mass, Mass number

Each number tells part of the identity of the atom

The Atomic number is the same as the number of protons in the atom ( protons have a positive charge )

The Atomic mass is the same as the neutrons and the protons combined ( neutrons have a neutral charge )

The number of electrons is the same as the number of protons ( electrons carry a negative charge )

Atoms

The pattern for drawing an atom is 2,8,8,8...

Valance electrons are electrons on the outermost shell of an atom

Balancing Equations

The reactants and on the left side and the products would be on the right. The arrow means to yield

Chemical Change: Changes in which one or more substances are combined or broke apart to form a new substance.
