It has 12 neutrons.
A neutral magnesium atom has 12 protons ans 12 electrons.
Lead has a total of 82 subatomic particles, which includes 82 protons and typically 126 neutrons in its most common isotope. Electrons can vary in number based on the charge of the ion.
There are 18, 20 or 22 neutrons.
Hydrogen typically has 0 neutrons.
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
The correct name of the ion Mg2+ is magnesium ion.
An Mg2+ ion has lost two electrons, resulting in a total of 10 electrons. Magnesium normally has 12 electrons but when it forms a 2+ ion, it loses two electrons.
Mg has 12 protons, 12 electrons and 12 neutrons.Mg^2+ ion has 12 protons, 10 electrons and 12 neutrons. The number of protons and neutrons remains the same, but since the ion now has a 2+ charge, it has lost 2 electrons.

Mg2+
Magnesium, ion (Mg2+)
Magnesium forms a simple ion with a 2+ charge, typically written as Mg2+.
The ion symbol for magnesium is Mg2+ as it loses 2 electrons to achieve a stable electron configuration.
it is +2. the ion is represented as Mg2+.
There are 10 electrons in Mg2+ because the atomic number of magnesium is 12, which means it normally has 12 electrons. When it forms a 2+ ion, it loses 2 electrons, leaving 10 electrons in the Mg2+ ion.
Any atom of magnesium will have 12 protons.Neutral atoms of Mg-24 will have 12 neutrons and 12 electrons. Mg-25 has 13 neutrons and Mg-26 has 14 neutrons. A magnesium ion will have either 10 or 11 electrons.
Li-6 has 3 neutrons and Li-7 has 4 neutrons.
