Question

the overall negative charge in tio₂ is -4. what is the charge of the titanium ion? +2 -4 -2 +4

Explanation:

Step1: Determine the charge of oxygen ion

In \(TiO_2\), oxygen ion (\(O^{2 -}\)) has a charge of \(- 2\).

Step2: Calculate the total charge of oxygen ions

Since there are 2 oxygen ions in \(TiO_2\), the total charge of oxygen ions is \(2\times(-2)=-4\).

Step3: Find the charge of titanium ion

Let the charge of titanium ion (\(Ti^{x+}\)) be \(x\). According to the rule that the sum of charges in a compound is zero (\(x+(-4) = 0\)), we can solve for \(x\).

$$x-4=0$$

$$x = 4$$

Answer:

\(+4\)
