Chemical Bonding

Front

What are valence electrons?

Back

Electrons in the outer shell of an atom that are involved in forming bonds.

Front

What kind of bond forms between two nonmetals?

Back

Covalent bond, where atoms share electrons.

Front

What is a polar covalent bond?

Back

A type of bond where electrons are shared unequally between two atoms, resulting in partial charges.

Front

What happens to an atom when it loses two electrons?

Back

It becomes a positively charged ion with a charge of +2.

Front

In an ionic bond, what charge does the atom with higher electronegativity have?

Back

Fully negative charge, as it attracts electrons more strongly.

Front

What is an ionic bond?

Back

A bond formed between a metal and a nonmetal where electrons are transferred.

Front

Define electronegativity.

Back

The ability of an atom to attract electrons in a chemical bond.

Front

What is a metallic bond?

Back

A bond formed between metal atoms where electrons are shared in a 'sea' of electrons.

Front

What is the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What is a nonpolar covalent bond?

Back

A bond where electrons are shared equally between two atoms, resulting in no charge separation.
