Question

How can I find valence electrons on the periodic table?

Answer 1

The valence electrons are found based on where the element is on the periodic table.

1. Locate the element on the periodic table.
2. Counting along the row/period, count the number of boxes to your element.

This will be how many valence electrons there are.

For example:
Carbon - there are four boxes in the row including the box with carbon in it, and there are four valence electrons in carbon.

Please note: This will only work for the first 20 elements.
