Types of Chemical Bonds Review

Atoms form chemical bonds to achieve a full valence shell like noble gases (8).

In metallic bonding, electrons are delocalized and move freely among the metal atoms.

Oxygen will gain 2 electrons to achieve a full valence shell.

Ionic compounds are good conductors of electricity when dissolved in water.

Metallic bonds are formed between metal + metal.

A covalent bond is formed when two nonmetals share electrons.

An ionic bond is formed when electrons are transferred from one atom to another, typically between metals and nonmetals.

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms.

A nonpolar covalent bond is a type of bond where electrons are shared equally between two atoms.
