Question

Quizplus · Accepted Answer

The formula and charge of the silicate ion can be determined by counting the number and charge of the atoms in the ion. In this case, there are 4 oxygen atoms (-8 charge) and 1 silicon atom (+4 charge), giving a total charge of -4. The correct formula for this ion is SiO4^4-. Choice B is the only option that contains this correct formula for the silicate ion.
