yes they all have 3 parts
A molecule of of water contain 3 atoms.
Yes, 2 times 3 atoms in 2O3 = 6 atoms = 3 times 2 atoms in 3O2
Chemical name for CaSO4 is calcium sulphate. It has 4 oxygen atoms in 1 molecule. So it has 12 oxygen atoms in 3 molecules.
3 Ni(OH)2 contain six oxygen atoms.
The chemical formula of water is H2O; water contain two hydrogen atoms and one oxygen atom: 2 + 1= 3 atoms.
A molecule of of water contain 3 atoms.
An atom contain protons, neutrons and electrons.
Sulfur difluoride molecule contain 3 atoms.
Silicon dioxide is SiO2 and contains 3 atoms.

Iodide is the I- ion, so it contains no oxygen atoms at all. Perhaps you meant iodate. It has 3 oxygen atoms per iodine atom: (IO3)-.
Three atoms, because theirs two Na and one S .
Yes, 2 times 3 atoms in 2O3 = 6 atoms = 3 times 2 atoms in 3O2
The chemical formula of water is H2O; the molecule contain 3 atoms.
The molecule of nitrogen dioxide contain 3 atoms (one of N and two of O).
Chemical name for CaSO4 is calcium sulphate. It has 4 oxygen atoms in 1 molecule. So it has 12 oxygen atoms in 3 molecules.
3 Ni(OH)2 contain six oxygen atoms.
