Answer:

Group 4a elements

Group 4A (or IVA) of the periodic table includes the nonmetal carbon (C), the metalloids silicon (Si) and germanium (Ge), the metals tin (Sn) and lead (Pb), and the yet-unnamed artificially-produced element ununquadium (Uuq). The Group 4A elements have four valence electrons in their highest-energy orbitals (ns2np2).
