An ion form when an element:

• gains or loses protons
• gains or loses electrons
• gains or loses neutrons
• gains or loses radiation

Electrons involved in chemical bonding.

• valence

• ionic

• covalent

• metallic

Each dot on a dot diagram represents one

• proton

• atomic mass unit

• energy level

• valence electron

When an atom gains electrons, it becomes a

• positive ion

• negative ion

• neutral ion

• neutral atom

What two types of atoms make a covalent bond?

• 2 Nonmetals

• 1 Nonmetal and 1 Metal

• 2 Metals

• 2 Noble Gases

How many atoms are shared in a single bond?

• 2 pairs

• 4

• 2

• 1

Atoms want

• a full outer shell of electrons

• one electron short of a full shell

• kit kats

• to be loved

Why do atoms bond?

• They typically don't bond

• To add or take away energy levels

• To have a full valance shell.

• To have a full inner shell
