Ok so I know the atomic mas for Al is 26.98 which would round to 27 and it has 13 protons and electrons. And I know 27-13=14 so Al should have 14 neutrons.
What I don't know is how to find the neutrons in the ones that are like 27Al or 32S.
Can anybody tell me how to find the neutron on those because i dont really understand it.
Thanks

So, you know that there are 14 neutrons in one Aluminum. The number before an atomic symbol is the "coefficient," which means that there are 27 Aluminum atoms. All you do is multiply 14 by 27 and get your answer.
Same thing with Sulfur. The atomic mass for Sulfur is 32 and the number of protons/atomic number is 16. 32-16=16. Now there are 32 Sulfur atoms, so 32 times 16 gives you your answer.
