Oxygen and sulfur are quite similar.


The way elements are grouped into columns on the periodic table places those that show similar properties into the same column.

Oxygen and sulfur are both in column 16. While they may physically look quite different, their chemical properties are really quite similar.

Both form -2 charged ions, so that ionic compounds they make have similar formulas: #H_2O# and #H_2S# for example.
