How many electrons does S2- have if sulfur has an atomic number of 16?

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-.


How many electrons are there in ion os S2?

Sulfur's atomic number is 16. Therefore, neutral sulfur has 16 protons and 16 electrons. Since we're dealing with S2-, we need to add 2 electrons to that, giving 18 total.

What is the symbol for an ion with 16 protons 16 neutrons and 18 electrons?

S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
