Calculate the molarity of a solution containing 10.0 grams of
sulfuric acid in 500 ml of solution.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
