... The metals (Na, Mg, Al) all tend to lose their outer valence electrons (be oxidised) and hence act as reductants. The non-metals (P, S, Cl) are increasingly strong oxidants as EN increases and AR decreases, causing them to attract electrons more strongly. Si is a metalloid and hence any redox proper ...
