Front

What is an ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net charge.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions (lost electrons), while anions are negatively charged ions (gained 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 type of bond is formed when electrons are shared between atoms?

Back

Covalent Bond.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move.
