• negative ion
• neutral ion
• neutral atom

• Blue
• Red
• Green

What usually forms the negative ion?

• nonmetals

• metal

• none

A covalent bond forms when atoms ___________ electrons.

• gain

• share

• increase

• transfer

Which type of bond has a transfer of an electron from on atom to another?

• Polar Covalent 
• Non Polar Covalent
• Ionic
• Metallic

Chemical bonds form when atoms

• combined nuclei
• give up neutrons
• gain protons
• share or transfer electrons

______ molecules are found in nature as pairs of two atoms of the same type covalently bonded together.

• Diatomic

• Monatomic

• Polyatomic

• Network

Why do bonds form?

• To fill the valence shell of electrons for the elements involved
• to release energy stored in the bonds
• because whenever you mix two chemicals, there will be a reaction
• because of attraction
