you don't calculate it, you look at the number that is usally above the chemical symbol on the Periodic Table.
its the same number as the protons
the atomic number minuse mass number
the Atomic Mass number is the number of protons/electrons in an atom
because an atomic number is the same as the number of electrons in an atom (not ion)
The atomic weight minus the number of protons = the atom's neutrons.
Atomic mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
You calculate the number of neutron in the nucleus of an atom by : atomic mass - atomic number = neutron number. :) hope this helps

Look up the atomic number of the element. The atomic number is the number of protons, in a neutral atom this is the same as the number of electrons.
The atomic weight minus the number of protons = the atom's neutrons.
Atomic mass is simply the sum of the number of protons and the number of neutrons. If an atom has "A" protons and "B" neutrons, its atomic mass is A + B.
Atomic weight minus number of protons.
The number of protons in a atom is equivalent to its atomic number. Hydrogen's atomic number is 1, there fore it has 1 proton. Coppers atomic number is 29 so it has a proton count of 29. And so on.
you look at either the atomic number or the number of electrons. That's the number of protons.
neutron can be calculated by subtracting the atomic number of the particular atom from its mass number.
