Fill in the Blanks

What is this called?

Periodic Table

Each square =
one atom.

Each square is called a tile or an atom.

Atomic Number

Symbol

AMU or Atomic Mass

Elemental Molecules are bonded by the same atoms.

Compound Molecules are bonded by different types of atoms.

Periodic Table

Notice that each atom has one or two letters; never more.

If it has 2 letters it's ALWAYS a capital letter and lower case letter.
