Chemical bonding

A bond between metal and non metal is called

• covalent bond

• ionic bond

• metallic bond

• transfer bond

Predict the bond that form between Be and F

• Covalent

• Ionic

What kind of bond form when atoms share electrons?

• Covalent

• Ionic

• Metallic

• Non metallic

If an atom loses two electrons what charge will it have?

• -1

• -2

• +1

• +2

Which particle is responsible for bonding?

• Electrons

• Protons

• Nucleus

• Neutrons

Which element is most likely to form 2 bonds?

• Carbon

• Fluorine

• Nitrogen

• Sulfur

The bonds in Na2O are best described as

• a covalent, because valence electrons are shared.

• covalent, because valence electrons are transferred.

• ionic, because valence electrons are shared.

• ionic, because valence electrons are transferred.

Atoms gain or lose electrons to become stable by satisfying this rule.

• Ionic law

• Lewis structure rule

• Periodic law

• octet rule
