Which statement correctly describes the ratio of barium ions to carbonate ions in barium carbonate?

A barium ion has a +2 charge, and a carbonate ion has a –2 charge. Therefore, the ratio is 1:1.

A barium ion has a +2 charge, and a carbonate ion has a –1 charge. Therefore, the ratio is 1:2.

A barium ion has a +1 charge, and a carbonate ion has a –2 charge. Therefore, the ratio is 2:1.

A barium ion has a +1 charge, and a carbonate ion has a –3 charge. Therefore, the ratio is 3:1.
