# What is the charge on an atom that has 12 protons, 10 electrons and 12 neutrons?

The charge is $+ 2$........
There are 2 more protons, massive fundamental particles of positive charge, than electrons, massless fundamental particles of negative charge. And thus the charge is $+ 2$.
You should be able to tell me the name of the element. If $Z = 12$, what is it? You should also be able to tell me the isotope. What are they?
