When a copper element is found not in a compound with another element, it is only one. The diatomic molecules are nonmetals. Sulfur (also a nonmetal) tends to be found in groups of eight when it is elemental.
Copper is an element. You can have a single atom or many atoms and it's still copper.
The answer is 47,128 x 1023 atoms.
Metals are giant structures of atoms held together by metallic bonds. "Giant" implies that large but variable numbers of atoms are involved - depending on the size of the bit of metal. Most metals are close packed - that is, they fit as many atoms as possible into the available volume. hope this helps :)
Copper(I) oxide (Cu2O) contains 3 atoms: 2 copper atoms and 1 oxygen atom.
Copper phosphate has the chemical formula Cu3(PO4)2. To determine the number of atoms, you need to add up the atoms in each element present. In this case, there are 3 copper atoms, 2 phosphorus atoms, and 8 oxygen atoms, totaling 13 atoms in copper phosphate.

In one formula unit of copper sulfate (CuSO4), there are three oxygen atoms.
A molecule of copper sulfate (CuSO4) contains one copper atom, one sulfur atom, and four oxygen atoms, totaling to a total of six atoms.
Copper is normally encountered as metal which is a giant lattice of atoms.
1 mol Cu Atoms (6.02x10^23 atoms)
The molar mass of copper is 63.5 g/mol. Using this, you can calculate that in a 12.0 gram sample of copper, there are approximately 0.189 moles of copper. Since 1 mole of a substance contains 6.02 x 10^23 atoms (Avogadro's number), the number of atoms in 0.189 moles of copper would be around 1.14 x 10^23 atoms.
Copper(II) sulfate pentahydrate, CuSO4•5H2O, contains one copper atom, one sulfur atom, four oxygen atoms, and ten hydrogen atoms per molecule.
