How can you determine the valence electrons in calcium?
Is there any easy way to remember which group on the periodic table corresponds to the number of valence electrons?
Yes, actually. Each group number corresponds to the number of valence electrons in the elements that are in that group. So for example, the elements in group 1 all have 1 valence electron, the elements in group 2 all have 2 valence electrons, and so on.
