Wha is the relationship between the group number and the number of valence electrons

Answer 1

The group number of an element indicates the number of valence electrons present in its outermost shell. For example, elements in group 1 have 1 valence electron while elements in group 8 have 8 valence electrons. This relationship can be observed in the periodic table as elements are arranged in order of increasing atomic number and grouped according to their valence electron configuration. Therefore, the group number and the number of valence electrons are directly related.
