Question

Oxide has a -2 charge. What is the overall negative charge in the formula, Ti*O_{2} which contains 2 oxide ions?

2 • -2 = ?
-2
+4
-4
+2

Answer 1

-4

Step-by-step explanation:

The overall negative charge in the formula Ti*O2 which contains 2 oxide ions, each with a -2 charge, is -4.

The total negative charge can be calculated by adding up the charges of all the oxide ions:

2 oxide ions x -2 charge/ion = -4

So, the overall negative charge in the formula Ti*O2 is -4.
