First it helps to know the chemical formula: CuSO4
The number in the subscripts indicate the number of atoms of an element in the compound. If there is no number, then it is implied that there is only one atom. So, there is one atom of copper, one atom of sulfur, and four atoms of oxygen; for a total of six atoms.

Copper sulfate has CuSO4 as its formula. Copper sulfate is also written copper (II) sulfate.

Copper sulfate (CuSO4) has 6 atoms and 3 chemical elements.
The "excess" metallic copper produced by adding zinc metal to a copper sulfate solution comes from exchanging zinc atoms from the metal for copper atoms from the copper sulfate solution. During the reaction, the zinc atoms are ionized to cations and the copper cations from the solution are reduced to neutral atoms.
Copper Sulfate is CuSO4. Therefore, it has 1 atom of Copper, 1 atom of Sulfur, and 4 atoms of Oxygen.
Copper sulfate is a salt composed of one copper atom, one sulfur atom and four oxygen atoms.
The anhydrous copper(II) sulfate molecule has four oxygen atoms.
Copper sulfate crystals are a compound, not an element. The compound is formed by combining copper, sulfur, and oxygen atoms.

I think there is one atom of copper and four atoms of sulfur but you should get a second opinion. I am 98% sure this is correct.

The color fades as there is a discharge of copper two ions to form copper atoms
