Chemical Bonds

The chemical bond formed when two atoms share electrons is call a(n)

• covalent bond

• ionic bond

• metallic bond

• electron bond

An ionic bond is formed when

• Valence electrons are shared.

• Valence electrons surround the cations.

• Valence electrons are transferred between atoms.

• Valence electrons are completely transferred between two metals.

• Their inner electron shell is filled

• They are able to bond to fill their outer shell

• None of the above, Noble Gases are highly reactive
