Understand the Problem

The question is asking how to determine the valence of a nonmetal element based on its number of valence electrons. It prompts the user to create a rule for this process, excluding hydrogen from consideration.

Answer

Subtract valence electrons from eight.

The final answer is to determine the valence of a nonmetal element, subtract the number of valence electrons in the atom from eight.

Answer for screen readers

The final answer is to determine the valence of a nonmetal element, subtract the number of valence electrons in the atom from eight.

More Information

Nonmetals aim to complete their outer electron shell to achieve a stable electron configuration, usually eight in total.

Tips

Common mistakes include not recognizing that the subtraction is done from eight or miscounting valence electrons.
