Ionic Bonds

Front

What is an anion?

Back

An anion is a negatively charged ion that gains electrons.

Front

Where are valence electrons located in an atom?

Back

Valence electrons are found in the outermost energy levels of an atom.

Front

How does oxygen become an oxide ion?

Back

Oxygen becomes an oxide ion by gaining 2 electrons.

Front

What part of the atom is involved in bonding?

Back

Bonding involves valence electrons.

Front

How many valence electrons do most atoms need to be stable?

Back

Most atoms need 8 valence electrons to be stable.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is the charge of a cation?

Back

A cation is a positively charged ion that loses electrons.

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 8 electrons.

Front

What happens to the energy when an ionic bond forms?

Back

Energy is released when an ionic bond forms, making the process exothermic.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.
