Iron-56 or 56Fe 56 protons makes it iron. If you add the protons and neutrons, you find the mass, which is 56.

Iron FE
Iron (Fe)
26 It has 26 protons, 26 electrons and (mostly) 30 neutrons, but 28, 31 and 32 neutrons are natural isotopes of iron as well (though less than 10%).
In a neutral iron (Fe) atom, the number of protons is 26, which is the atomic number of iron. The number of neutrons can vary, but the most common isotope of iron, Fe-56, has 30 neutrons. Since the atom is neutral, it will have an equal number of electrons as the number of protons, so it also has 26 electrons.
Iron has 26 protons, and since protons and electrons are usually the same there are 26 electrons in Iron. There is 30 neutrons. So protons=26, electrons=26, neutrons=30.
protons 26 electrons 26 neutrons Iron will have 26 electrons 26 protons (they are = because the atom is neutral) and it will have 30 neutrons (because protons + neutrons= your atomic weight) electrons have virtually no mass If the iron atom had a +2 charge there would be two less electrons than protons. 26 protons 24 electrons 30 neutrons.
This would be magnesium, based on the number of protons. Since the protons is equal to the number of electrons it is a neutral atom. Given the number of protons in the atom, the isotope would be magnesium-26.
(a) a sodium atom with 11 protons, 11 electrons, and 12 neutrons (b) a calcium atom with 20 protons, 18 electrons, and 20 neutrons (c) a helium atom with 2 protons, 2 electrons, and 2 neutrons (d) an iron atom with 26 protons, 26 electrons, and 30 neutrons
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons

A positive ion.
Protons: 21 Neutrons: 29 Electrons: Normally 21
Iron has 26 protons, and since protons and electrons are usually the same there are 26 electrons in Iron. There is 30 neutrons. So protons=26, electrons=26, neutrons=30.
The 46 = #Neutrons + #Protons and 22 = #Protons so... # Neutrons = 26

22: The atomic number is defined as the number of protons in the atom, but since the atom is neutral, the number of protons must be the same as the number of electrons.
In a neuteral atom no. of electrons=no. of protons no. of protons=22 and atomic number is given by no. of protons=22 Hence Atomic number is 22
