Indicate the number of valence electrons in each of the

Solution 57QPStep 1 of 2:The goal of the problem is to indicate the number of valence electrons in given elements.Valence electrons are the electrons in the outermost energy level of an atom. We can identify the valence electrons of each element using the periodic table. The group numbers in the periodic table indicate the number of valence electrons of the element. The valence electrons occupy the s and p orbitals of the atom with the highest principal quantum number n.
