We refer to "molecules" of sodium sulfate as formula units. The formula is Na2SO4. The molar mass is 142 g/mole. And sulfur (S) is 32 out of the entire 142 g. So, percent sulfur is 32/142 (x100%) = 22.5%
Magnesium sulfide contains two elements: magnesium and sulfur.
Hydrogen sulfide (H2S) contains 2 elements: hydrogen and sulfur. It consists of 2 hydrogen atoms and 1 sulfur atom.
Two electrons are transferred to sulfur from barium to form barium sulfide.
Each molecule of hydrogen sulfide contains two hydrogen atoms and one sulfur atom.
Sulfide is S-2. It can combine on many different kinds of atom. There are thousands of sulfides.
In one formula unit of sodium sulfide (Na2S), there are 3 atoms - 2 atoms of sodium (Na) and 1 atom of sulfur (S).
In one molecule of Na2S (sodium sulfide), there are 2 atoms of sodium (Na) and 1 atom of sulfur (S).
Many metals form ionic sulfides containing the S2- ion, , for example sodium, Na2S sodium sulfide. Iron forms a sulfide, FeS, iron(II) sulfide and a disulfide, containing the S22- ion, iron, iron(II) disulfide, FeS2 , "fools gold"
Sodium loses one electron to form a Na+ ion. Sulfur gains two electrons to form a sulfide ion, S2-.
There are 16 protons in the sulfide ion, which is similar to the sulfur atom.
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
The chemical formula of sodium sulfideis Na2S. The sodium cation is Na+ and the sulfide anion is S2-.
Answer
Magnesium sulfide contains two elements: magnesium and sulfur.
Zinc sulfide has two elements: zinc (Zn) and sulfur (S).
Compounds combined with sulfur include hydrogen sulfide (H2S), sulfur dioxide (SO2), sulfuric acid (H2SO4), and various sulfides like iron sulfide (FeS) and zinc sulfide (ZnS). Sulfur forms a wide range of compounds due to its ability to bond with many different elements.
Sulphur (also sulfur) is an element. It can be both uncharged and charged. In pure form sulfur is uncharged. As sulfide ions is has charge -2. In many molecules (like the amino acid custeine) and polyatomic ions (like the sulfate ion) sulfur does not have a formal charge, but can have many different states of oxidation.
