Question

how many protons does an ion with 10 electrons and a charge of +1 contain? 8 9 12 11 10

Explanation:

Step1: Recall ion charge formula

The charge of an ion is given by \( \text{Charge} = \text{Number of protons} - \text{Number of electrons} \).

Step2: Rearrange formula to find protons

We know charge is \( +1 \) and electrons are \( 10 \). Rearranging the formula: \( \text{Number of protons} = \text{Charge} + \text{Number of electrons} \).

Step3: Substitute values

Substitute charge \( = +1 \) and electrons \( = 10 \) into the formula: \( \text{Number of protons} = 1 + 10 = 11 \).

Answer:

11
