Ionic and covalent bonds

Front

What type of bond is formed in NH₃?

Back

Covalent Bond

Front

What do atoms that form positive ions tend to do?

Back

Lose electrons

Front

Why do atoms bond?

Back

To satisfy the octet rule

Front

If an atom has 1 valence electron, what is more likely to occur: gain 7 electrons or lose 1?

Back

Lose 1

Front

What does ionic bonding involve?

Back

The transfer of electrons

Front

Define ionic bond.

Back

A bond formed through the transfer of electrons from one atom to another, resulting in the attraction between oppositely charged ions.

Front

Define covalent bond.

Back

A bond formed when two atoms share one or more pairs of electrons.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What happens to an atom that gains electrons?

Back

It becomes a negatively charged ion (anion).

Front

What happens to an atom that loses electrons?

Back

It becomes a positively charged ion (cation).
