Front

What are cations?

Back

Cations are positively charged ions that are formed when an atom loses one or more electrons.

Front

What are anions?

Back

Anions are negatively charged ions that are formed when an atom gains one or more electrons.

Front

Which elements typically form cations?

Back

Elements on the left side of the periodic table, such as metals.

Front

Back

Elements on the right side of the periodic table, such as nonmetals.

Front

What is the significance of the periodic table in determining ionic compounds?

Back

The periodic table helps predict how elements will bond based on their position, including their tendency to lose or gain electrons.
