Question

Quizplus · Accepted Answer

The first ion contains barium and sulfur, with a Superscript 1 Upper 1 P12+ indicating that the barium has a charge of +2 and the sulfur has a charge of -2, resulting in a neutral compound. The second ion contains tin and sulfur with a Superscript 1 Upper 1 P12+ indicating that the tin has a charge of +2 and the sulfur has a charge of -2, resulting in a neutral compound. The third ion contains selenium and sulfur, with a Superscript 1 Upper 2 P12- indicating that the selenium has a charge of -2 and the sulfur has a charge of -2, resulting in a negative compound. The best choice is B, with barium and tin having a Roman numeral II after their names to indicate their +2 charge and selenium becoming selenide because of its negative charge.
