A bond between a metal and a metal is called a(n) *

• covalent bond

• ionic bond

• metallic bond

• transfer bond

Why do all bonds form? *

• filling the outermost energy level to become more stable

• to make all atoms the same and more likable.

• to make other atoms unstable and less happy.

• to make all atoms different

The metallic element will __________ an electron to the Non-metallic element and the metallic element will become a __________ ion. *

• transfer ; positive

• share ; positive

• transfer ; negative

• share ; negative

Nonpolar bonds are: *

• elements that only exist when paired with itself.

• bonds that share a pair of electrons equally

• bonds that share a pair of electrons unequally

• ionic bonds that share a pair of electrons equally

A triple bond is a ________ bond produced by the sharing of _______ pairs of electrons. Mark only one oval.

• covalent; three

• covalent; six

• ionic; three

• ionic; six

The metallic bond forms an electron cloud around the metal atoms called a: Mark only one oval.

• delocalised sea of electrons

• nonpolar covalent bond

• diatomic shell

An atom with 3 valence electrons "wants" a full shell, so it can either gain 5 or lose 3. Which is more likely to occur? Mark only one oval.

• Gain 5

• Lose 3

• Nothing
