15P = 1s2 2s2 2p6 3s2 3p3
16S = 1s2 2s2 2p6 3s2 3p4
P forms P2O5 (actually P4O10) and S forms SO3.
P2O5 and SO3 added to water form H3PO4 and H2SO4 and both are strong acids.
P has three 3p electrons and none are paired.
S has four 3p electrons and two of them are not paired.
Two properties of non-metallic elements and their atoms are as follows.
property 1 has an oxide that can form a strong acid in water
property 2 has no paired 3p electrons
Which properties do phosphorus and sulfur have?
