an atom of the isotope sulfur-31 consists of how many protons, nuetrons and electrons?
An atom of carbon-14 has how many protons, nuetrons and electrons? Atomic number of all atoms of carbon = 6. This means all atoms of carbon have 6 protons. It also means that because atoms have the same number of proton as electrons, there are 6 electrons. Finally 14 is the mass number which is the number of protons added to the number of neutrons. As there are 6 protons, there must be 14-6 = 8 neutrons.. So 6 protons, 6 electrons and 8 neutrons.
Just apply this to sulphur which will have an atomic number of 16
