Front

Define valence electrons.

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

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

How does the electron configuration change when an atom becomes an ion?

Back

The electron configuration changes by either losing or gaining electrons, affecting the total number of electrons.
