Answer:

d. 10

Explanation:

The 24 means the atomic mass and twelve means the number of electrons. You subtract the number of electrons from the atomic mass. 24-12=12

Then, since there's +2, you subtract 2 from 12 which equals 10 which means there are 10 electrons now.

The confusing thing is that + means subtract and - means add here.

Hope this helps.
