Manganese has 25 protons, 25 electrons and 30 neutrons.
Manganese has 25 protons, 25 electrons and 30 neutrons.
Manganese (Mn) has an atomic number of 25, which means it has 25 protons and, in a neutral atom, 25 electrons. The most common isotope of manganese has a mass number of 55, which means it has 30 neutrons (55 - 25 = 30). Therefore, a neutral manganese atom contains 25 protons, 30 neutrons, and 25 electrons.
The atomic number of magnesium is 12. So there are 12 protons
Manganese: 25 protons, 30 neutrons, 25 electrons. Magnesium: 12 protons, 12 neutrons, 12 electrons. Argon: 18 protons, 22 neutrons, 18 electrons. Potassium: 19 protons, 20 neutrons, 19 electrons. Gold: 79 protons, 118 neutrons, 79 electrons. Hydrogen: 1 proton, 0 neutrons, 1 electron. Fluorine: 9 protons, 10 neutrons, 9 electrons. Silicon: 14 protons, 14 neutrons, 14 electrons. Boron: 5 protons, 6 neutrons, 5 electrons. Bromine: 35 protons, 45 neutrons, 35 electrons.

25 protons 25 electrons normally 30 neutrons but it can vary between 21 and 40.
The element manganese has 25 protons in its nucleus. You'll recall that the number of protons in an atom gives it its chemical identity, and only that. It will also have 25 electrons when the atom is in the neutral state. (Manganese normally "loans out" electrons in chemical reactions.) There are 30 neutrons in the only stable isotope of manganese, but there are a number of different isotopes of this transition metal. They've been synthesized, of course, and the number of neutrons ranges from 19 through 44. A link can be found below.
