Question

Vocaloid · Answer

thoughts on this one?

looking at the periodic table, sulfur and phosphorus are in the same period (row) which means there's no major difference in shielding.

the main difference you need to consider: sulfur has one more proton than phosphorus. this will result in sulfur having a greater positive effective nuclear charge in the nucleus. if the nucleus is more positive, do you think it will pull more or less strongly on the valence electrons?
