Question: how many protons and electrons are present in s?
Answer: In the case of Sulphur the atomic number is 16 - that means the number of protons is 16. An atom always has the same number of protons as electrons so there are 16 electrons also. The difference between the mass number and atomic number (32 - 16) is the number of neutrons so Sulphur has 16 neutrons also.
