Question

What is the number of protons in an atom of carbon-12?

Answer 1

For all carbon, `Z, "the atomic number"=6`.

Explanation:

And by definition, if `Z=6`, there are are 6 protons, 6 massive, positively charged particles, in each carbon nucleus; this is what characterizes the element as carbon.

How many neutrons, massive, neutrally charged particles are there in a `"^12C` atom?
