The ion S(2-) has 16 protons and 18 electrons.
Neutral-charge sulfur, regardless of its isotope, has 16 electrons, the same number as for protons.
A sulfide ion, S2-, has 18 electrons. A neutral sulfur atom has 16 electrons, the same as the number of protons, which is the atomic number. Since electrons have a negative charge, a sulfur atom must gain two extra electrons in order to form the sulfide ion with a charge of 2-.
Oxygen-16 has 16 electrons (the 16 refers to the number of electrons, so Oxygen-15 if it exist, will have 15 valence electrons)
Look at the periodic table. You see that the element that has 16 protons is Sulfur. Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-. So, the symbol of the ion would be S2- .
Its charge must be +1, no matter how many neutrons are there.
There are 16 electrons in this ion. 7 from nitrogen, 8 from oxygen and the other one is from the ionic charge.
i think it depends how many electrons it has. then you do something like subtract the electrons from the protons. electrons are negative, protons are positive.
There are 16 electrons from the oxygen atoms, one from the hydrogen atom and one from the charge, that makes 18 electrons altogether. Its valency is 1.

Sulfur normally has 16 electrons, so....,S 2-===A 2 - charge on the anion.
16 protons, and if it isn't an ion ("isn't an ion" means that it has no electric charge), it has 16 electrons. on average, sulfur has 16.065 neutrons, but that's averaged out, so it's a weird number. let's just say most sulfur has 16 neutrons.
16 electrons
Oxygen-16 has 16 electrons (the 16 refers to the number of electrons, so Oxygen-15 if it exist, will have 15 valence electrons)
The atomic number is 16, so a sulfur atom has 16 protons in the nucleus and 16 electrons in the electron cloud.
