copper oxide is a molecule / compound.
Copper sulphate is either CuSO4 or Cu2(SO4)3 depending on the oxidation number of the copper atom. Therefore, there are three types of atoms in copper sulphate - copper, sulfur and oxygen.
A formula unit for copper (II) sulfate, with formula CuSO4.
Copper on the Periodic Table of Elements is Cu. Copper is 1 atom. Sulphur on the Periodic Table of Elements is S. Sulphur is 1 atom. Oxygen on the Periodic Table of Elements is O. Since there is a 4 next to the O, it's 4 atoms of Oxygen. 1 Atom of Copper + 1 Atom of Sulphate + 4 Atoms of Oxygen = 6 Atoms.
It is Copper(II) Chloride = CuCl2

An unstable atom is a radioactive atom.
Well obviously Hydrogen is the smallest atom because it only has one electron, this makes it unstable, but aside from that the period is 1.
A radioactive atom is an atom of an element with an unstable nucleus.
Any atom in the first family of the periodic table of elements is very unstable.
