How many electrons are there in Mg2 +? ۔
The magnesium atom is neutral, so it has the same number of protons and electrons, it has 12 protons. So it has 12 electrons.

How many electrons are there in Mg2 +? 3
See table IC. Mg is number 12, so it has 12 protons and 12 electrons.
The +2 charge of magnesium ion means that the number of protons is 2 times the number of electrons. To form a magnesium ion, 2 electrons are extracted from the outside of the magnesium atom.
The MG + 2 ion has 12 protons and 10 electrons = +12 + 10 = +2 charge.
The number of protons can only change when the atom is radioactive. The nucleus of the radioactive element emits an alpha particle consisting of 2 protons and 2 neutrons. This process is known as transfer. You can learn about radiation in chemistry or physics.

122 = 10
Atom number 12 is magnesium. The basic magnesium atom has 12 protons and 12 electrons.
The positive ion Mg + 2 results from the loss of 2 electrons in the Mg atom. Therefore, the Mg + 2 ion has only 10 electrons (although it had 12 protons).
