8 - The number of valence electrons in the atom = The valence of the element.
For example, if the number of valence electrons is 7, then the valence of the element would be:
8 - 7 = 1
For example, if the number of valence electrons is 7, then the valence of the element would be:
8 - 7 = 1
Make a rule : If you knew the number of valence electrons in a nonmetal atom, how would you determine the valence ...
