Types of Bonds (Introduction)

When two nonmetals share valence electrons, they form...

• an ionic bond

• a covalent bond

• a metallic bond

• the Fellowship of the Ring

When a metal gives valence electrons to a nonmetal, they form

• a metallic bond

• a dance circle

Ionic bonds are formed between atoms with

• a zero-to-small electronegativity difference

• a medium electronegativity difference

• a medium-to-large electronegativity difference

• similar haircuts

Covalent bonds are formed between atoms with

• a zero-to-small electronegativity difference

• a medium electronegativity difference

• a medium-to-large electronegativity difference

• matching shoes
