Question 3

Barium is in group 2 and sulfur is in group 6. In barium sulfide, BaS, there is one barium ion for every sulfide ion.

Which statement explains this ratio of ions?

[1]
A

Each barium atom loses six electrons and each sulfur atom gains six, so the 6+ and 6− charges cancel

B

Each barium atom loses two electrons and each sulfur atom gains two, so both ions have no overall charge

C

Each barium atom loses two electrons and each sulfur atom gains two, so the 2+ and 2− charges cancel

D

Each barium atom loses one electron and each sulfur atom gains one, so the 1+ and 1− charges cancel
