Question

a carbon ion has 6 protons, 6 neutrons, and 7 electrons. what is its overall charge? +1 -1 0 +2

Explanation:

Step1: Determine proton charge

Protons have a charge of +1 each. So total proton - charge = 6×(+1)= + 6.

Step2: Determine neutron charge

Neutrons have a charge of 0. So total neutron - charge = 6×0 = 0.

Step3: Determine electron charge

Electrons have a charge of - 1 each. So total electron - charge = 7×(-1)= - 7.

Step4: Calculate overall charge

Overall charge = total proton - charge+total neutron - charge+total electron - charge = + 6+0+( - 7)= - 1.

Answer:

B. -1
