Magnesium has atomic number 12 and so has 12 protons in the nucleus and 12 electrons in the neutral atom. It has three stable isotopes with 12, 13 or 14 neutrons. The neutrons have no real effect on the electronic structure.
The ground state consists of the 1st shell of two electrons and the 2nd shell of 8 electrons. The last two electrons begin the 3rd shell and reside in the subshell named 3s.
The last two electrons are the valence electrons.
Valency is not a word... but if you want to know the number of valence electrons that Magnesium has, it is 2. Magnesium's atomic number is 12.
If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
Atom Mg-26 in the ground state has 2 valence electrons. Magnesium (Mg) has an atomic number of 12, so it has 12 electrons in total. In the ground state, the electron configuration is [Ne] 3s2, which means it has 2 electrons in the outermost shell (valence electrons).
The total number of valence electrons in Boron's ground state is 2
The charge on a magnesium ion is determined by the number of electrons it gains or loses to achieve a stable electron configuration. Magnesium, with 12 protons, typically loses 2 valence electrons to form a 2+ charged ion. This loss of electrons allows the magnesium ion to achieve a full outer electron shell, which is more stable.

Yes, helium only has two electrons which makes up its valence electrons (also known as an outer shell) and magnesium also has two valence electrons.
Both are in the same group; accordingly, they have the same number of valence electrons (2).
For example calcium and magnesium.
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.

A fluorine atom in the ground state has 7 valence electrons.
Argon and Xenon have the same number of valence electrons, both are noble gases (group 18 that have 8 electrons).
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
