The atomic number of an element is equal to the number of protons in the nucleus of its atom. The atomic number is also known as proton number of the element. Further, in an atom, number of protons is equal to the number of electrons. Hence, atomic number is also equal to the number of electrons in an atom of the element. Thus,
The number of protons and electrons (in a neutral atom) are equal to the atomic number of the atom. For example in a, the number of protons and electrons in magnesium is 12.To find neutrons, you take the atomic mass of the atom and subtract the number of protons.For Magnesium, you subtract 12 from 25 to find the number of neutrons, which in this case is 13.he number of protons and electrons (in a neutral atom) are equal to the atomic number of the atom. For example in a, the number of protons and electrons in magnesium is 12.
