So when, say, elements in period 4 decreases accross the period, does it decrease until it is smaller than the biggest element in period 3? for example, is Bromine (period 4 group 17) smaller than Sodium (period three group 1)??<BR/><BR/>My school teacher says no because "all elements in period 4 is bigger than elements in period 3", but my sister who is in college says that bromine is smaller.Samuel K Lishttps://www.blogger.com/profile/12159214638133327670noreply@blogger.com
