tetra-ethyl lead means lead and ethyl taken four times in ethyl 7 atoms will be present there fore in tetra ethyl 28 atoms will be present.i9n tetra-ethyl lead 1 lead atom will be present so in total 28+1=29 atoms will be present in tetra-ethyl lead.
29 atoms are present in one molecule of tetraethyl lead

In each MOLECULE of Pb3PO4 there would be 3 lead atoms, but Pb3PO4 is not a correct formula. The formula for lead phosphate would be Pb3(PO4)2. There are still 3 lead atoms per molecule of the compound.
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
