How many atoms does a compound have?
Compounds are made of two or more atoms of different elements, such as water (H2O) and methane (CH4). Atoms are not drawn to scale. Molecules of compounds have atoms of two or more different elements. For example, water (H2O) has three atoms, two hydrogen (H) atoms and one oxygen (O) atom.
How can you tell how many atoms are in a molecule?
To find out the number of atoms: MULTIPLY all the SUBSCRIPTS in the molecule by the COEFFICIENT. (This will give you the number of atoms of each element.)

Which is heavier one oxygen atom or 10 hydrogen atom?
Oxygen atom is heavier than hydrogen atom because, the mass of one oxygen atom is 16u and that for one hydrogen atom is 1u. which is still less than that of one oxygen atom. Therefore, the mass of one oxygen atom is greater than that of 10 hydrogen atoms.
