What is the atomic number of S-2?
The atomic number of sulfur is 16 The number of protons is the same as the atomic number. The S-2 gains 2 electrons so it changes from 16 to 18. The atomic mass is 32. The atomic mass number minus the number of protons will give you 16 which is the number of neutrons. :)

What changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2

How can you figure out the number of neutrons in an atom?
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
