double covalent bond
If you wrote S8, people would think there were 8 sulfur atoms in the molecule. S is the symbol for the element sulfur, S8 is the symbol of an allotropic form.
If I undersstand your question correctly, a group of atoms that is joined by a covalent bond, and is neutral would be called a non-polar molecule.
Each molecule of Al2S3 is composed of one Al3+ ion. Since a mole is equal to 6.022 x 1023 molecules, there would be 6.022 x 1023 Al3+ ions in one mole of Al2S3.
i believe just one. H has a oxidation # of 1 and Cl has an oxidation # of -1. So in one molecule of HCl i think there would be just one. Isnt that almost the same thing as hydrochloric acid though??
2 atoms of S + 10 atoms of F = 12 atoms total

you would have 6.022 x 10^23 atoms (Avogadro's number)
In each sulfur trioxide molecule there is one sulfur atom and three oxygen atoms, giving a total of four atoms. In 1.14 moles of sulfur trioxide, there would be 1.14 x 6.02 x 10^23 = 6.87 x 10^23 molecules. Accordingly, there would be 4 x 6.87 x 10^23 = 2.75 x 10^24 atoms in total.
Sodium Sulfate is Na2SO4 and so there are 7 atoms in the molecule.
Sulfur dioxide.
A group of two or more atoms held together by chemical bonds would be termed a molecule.
0.45 mol BaSO4 have 2,698.10e23 sulfur atoms.
Sulfur Dioxide
Sulfur hexafluoride has covalent bonds.
Iron sulfide
A single molecule of table salt contains two atoms: sodium (Na) and chlorine (Cl). So a billion molecules of salt would require two billion atoms.
Oxygen is an element. The oxygen in our atmosphere typically combines with itself, as does the nitrogen, forming a diatomic molecule--O2. So the two atoms in a molecule of oxygen would both be oxygen atoms.
