Question

a nitride ion has 7 protons, 8 neutrons, and 10 electrons. what is the overall charge on this ion? -3 -2 0 +3

Explanation:

Step1: Calculate the charge of protons

Protons have a charge of \(+1\) each. There are 7 protons, so the total charge from protons is \(7\times(+1)= + 7\).

Step2: Calculate the charge of electrons

Electrons have a charge of \(-1\) each. There are 10 electrons, so the total charge from electrons is \(10\times(-1)=-10\).

Step3: Calculate the overall charge

The overall charge of the ion is the sum of the charges from protons and electrons. Using the formula \(Q = \text{Charge from protons}+\text{Charge from electrons}\), we substitute the values: \(Q=(+7)+(-10)=-3\).

Answer:

-3
