Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

How does losing electrons affect the charge of an atom?

Back

Losing electrons results in a positive charge.

Front

How does gaining electrons affect the charge of an atom?

Back

Gaining electrons results in a negative charge.

Front

What is the significance of the periodic table in determining valence electrons?

Back

The periodic table helps identify the number of valence electrons based on an element's group.
