Hey, I know this may sound stupid to most of you but i'm struggling with this and I have a test tomorrow and this is one of the questions.
Take, for example, Carbon.
How do I work out the number of protons, electrons, neutrons and the mass?
Is neutrons always the big number minus the small number? So, if I am correct,
N= 6 (or do you do 6-12?)

The atomic number 6 is the number of protons in an atom. (It is also the number of electrons in an atom).
The mass number 12 is the total number of protons + neutrons. So use it to calculate thr number if neutrons.
