Unit 5 Chemical Bonding Review

Front

What is a nonpolar molecule?

Back

A nonpolar molecule is one in which the electrons are all shared equally among the atoms.

Front

What happens to the ionic character of a bond as the electronegativity difference increases?

Back

The greater the electronegativity difference between two bonded atoms, the greater the percentage of ionic character in the bond.

Front

How are ions in most ionic compounds organized?

Back

The ions in most ionic compounds are organized into a crystal structure.

Front

What rule do atoms follow to gain or lose electrons for stability?

Back

Atoms gain or lose electrons to become stable by satisfying the Octet Rule.

Front

What do covalent compounds do with electrons?

Back

Covalent compounds share electrons between atoms.

Front

Define electronegativity.

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What is the Octet Rule?

Back

The Octet Rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What type of bond involves the transfer of electrons?

Back

Ionic bonds involve the transfer of electrons from one atom to another.

Front

What is a polar molecule?

Back

A polar molecule is one in which the electrons are unevenly shared, resulting in a partial positive and negative charge.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed by the sharing of electrons between two atoms.
