Front

What is a cation?

Back

A positively charged ion formed when an atom loses one or more electrons.

Front

What is an anion?

Back

A negatively charged ion formed when an atom gains one or more electrons.

Front

What happens to the electron configuration of an atom when it becomes a cation?

Back

It loses electrons, resulting in a positive charge.

Front

What happens to the electron configuration of an atom when it becomes an anion?

Back

It gains electrons, resulting in a negative charge.

Front

Why do metals tend to lose electrons?

Back

To achieve a stable electron configuration, often resembling the nearest noble gas.
