Question

select the correct answer. an ion has a net charge of 3+. if this ion has 8 protons, how many electrons does it have? a. 3 b. 5 c. 7 d. 8 e. 11

Explanation:

Step1: Recall charge formula

The net charge \( Q \) of an ion is given by \( Q = p - e \), where \( p \) is the number of protons and \( e \) is the number of electrons.

Step2: Substitute known values

We know \( Q = +3 \) and \( p = 8 \). Substituting into the formula: \( 3 = 8 - e \).

Step3: Solve for \( e \)

Rearrange the formula: \( e = 8 - 3 \). So \( e = 5 \).

Answer:

B. 5
