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: Determine proton charge

Protons have a charge of +1 each. With 7 protons, total proton charge is $7\times(+ 1)=+7$.

Step2: Determine electron charge

Electrons have a charge of -1 each. With 10 electrons, total electron charge is $10\times(-1)= - 10$.

Step3: Calculate overall charge

Overall charge = Proton charge+Electron charge. Neutrons are neutral and not considered in charge calculation. So, overall charge is $+7+( - 10)=-3$.

Answer:

-3
