Aluminum, element number 13. You can tell how many valence electrons an element has by looking at its group (column). This rule only applies for the metals and nonmetals, however. In other words, columns IA, IIA, (skip the middle section starting with Sc and ending with Zn) IIIA, IVA, VA, VIA and VIIA have 1, 2, 3, 4, 5, 6 and 7 valence electrons, respectively.
the element phosphorus
Selenium. As you go across the groups, not counting the transition metals, a valence electron is added.
Boron has 3 valence electrons.Boron has 3 valence electrons.
Boron has 3 valence electrons out of five total electrons.
