How do you figure out how many valence electrons an atom of an element has?

Find the family/group (the tall ones) that the element belongs to and count the families/groups (the tall ones) from left to right. The number of valence electrons is equal to the one's place of the family/group number.

Why are valence electrons important?

They indicate how the element will chemically react in the world.

What is a valence electron?

an electron on the outer shell of the atom
