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. :)
S is a non metal element. Atomic number of it is 16.
The same as in all sulfur atoms and ions of any kind: 16.
Sulfur is a non meta element. Atomic number of it is 16.
The sulfide ion, S2-.
pyrite is a mineral consisting of 2 elements, so it doesn't have an atomic number. pyrite consists of iron and sulfur; FeS2 (Fe=1 Iron atom & S2= 2 Sulfur atom; these three atoms make a pyrite molecule). i this helped
this elemnt has an atomic number that is double the atomic number of silicon?
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
You subtract the atomic number from the mass number.
The sulfide ion, S2-.
The ion with an atomic number of 16, mass 33 and 18 electrons is the sulfide ion S2-
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-.
it S2-, because when you add electrons, you are making the atomic radius bigger. In S2-, you add 2 electron, making it bigger. hope that helped.
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.

the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.

Subtract the atomic number from the atomic weight.
