Every element has its own unique atomic number. The atomic number tells how many protons are in 1 atom of that element. Since no 2 elements have the same same atomic number, no 2 elements have the same number of protons. Basically, the atomic # is the same as the # of protons. For example: Aluminum= ''Al'' has an atomic # of 13, so it has 13 protons.

The number of protons that an atom has is the same as the atomic number of the element. It is also the same as the number of electrons if the atom is neutral. If you are given the mass number of the atom, then subtract the number of neutrons and you will be left with protons.

The number of protons in an atom is equal to its atomic number, which is found on the Periodic Table. Each element has a distinct number of protons that determine its identity.

You can figure this out by either looking at the atomic number for that atom or to look at the amount of electrons the atom has. Both numbers should be the same.

If this atom has a balanced charge how many protons would you expect to find in this atom?

If an atom has a balanced charge, it means that the number of protons equals the number of electrons. So, you would expect to find the same number of protons as the atomic number of the element.
