The atomic number indicates the number of protons in the nucleus, and in a neutral atom it has the same number of neutrons. Therefore, for example, hydrogen is an element because it is an atom with a certain atomic number.

On the other hand, a compound is a mixture composed of two or more different elements. So, H2SO4 is made of three different elements, then it is a compound.
