Magnesium has 12 protons. Bear in mind that ionization has no effect on the number of protons, so the "2 plus" is unnecessary. Magnesium always has 12 protons, that is the definition of magnesium.

How many electrons and protons are present in Mg 2?
ans 12 atomic no. of Mg is 12 and in Mg2+ there is a lose of only 2 electrons so no. of protons shall be unchanged.
How many valence electrons does a neutral magnesium atom have?
12, the same as the number of protons indicated by magnesium having an atomic number of 12.
What element has 12 electrons 12 protons and 14 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.
How many protons and electrons in Be2 plus ION?
Be2+ ion has 4 protons and 2 electrons
What is the number of proton and electrons of magnesium ion?
Cl-1 has 17 protons and 18 electrons
Which has more protons aluminum or magnesium?
Magnisium has a different atomic mass to sodium plus they are in 2 separate periods, but im not sure about having more protons :)
How many protons does he plus ion possess?
The number of protons is 2.
How many electrons and protons are present in Mg 2?
ans 12 atomic no. of Mg is 12 and in Mg2+ there is a lose of only 2 electrons so no. of protons shall be unchanged.
Does a Mg2 plus ion have two more protons than an atom of Mg?
Absolutely not. Magnesium is magnesium, whether it's an ion or not. So it must have 12 protons. The number of electrons, however, is different. Neutral (non-ionic) magnesium has 12 electrons; the magnesium ion (Mg+2) has 10 electrons, which means it is isoelectronic with neon.
When an unstable magnesium nucleus undergoes alpha decay the nucleus formed is that of sodium neon magnesium aluminum or silicon?
Magnesium has 12 protons and 12 or so neutrons depending on the isotope. An alpha particle has 2 protons and 2 neutrons. So if magnesium loses 2 protons by shooting off an alpha particle, it will move 2 places down the periodic table and become neon. Neon has 10 protons.
How many electrons are usually in the outer orbit of a neutral atom of magnesium?
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
How many valence electrons does a neutral magnesium atom have?
12, the same as the number of protons indicated by magnesium having an atomic number of 12.
How many electrons are usually in the outer orbit of a neutral atom of magnesium Mg?
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
How many proton does He plus 2 ion possess?
The number of protons is 2.
What element has 12 electrons 12 protons and 14 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.
The name of the element that has 2 valence electrons and 12 protons?
Magnesium
How many protons and electrons are in the following ionsC4 plus?
The ion carbon C4+ has 6 protons and 2 electrons.
