Question
How do you find the number of valence electrons in an element?

Solution
Explanation :
The group number of the element normally specifies the number of valence electrons.
Group I and Group II elements have 1 and 2 valence electrons respectively; and the Group III metals have 3 valence electrons.
The trend is not so apparent with the transition metals in that the d electrons behave differently to the s and p electrons.
