There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. ... 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.

To write the electron config all we have to do is remove three electrons from the configuration for Mg. That leaves us with: 1s2 2s2 2p6 And that is the electron configuration for Mg 2+ , the Magnesium ion.

That means there are 13 electrons in a aluminum atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and three in shell three.
1442135
Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons.
158685
How many protons, neutrons, and electrons are in a neutral atom with the symbol 41Ca. A) 20 protons, 21 neutrons, 21 electrons.
378469
How many more electrons can fit in the valence shell of a hydrogen atom? One more since there is already one electron in the shell, and it is the first shell which can hold a max of 2 electrons. What type of ion does the magnesium atom, Mg, tend to form?
1081762
The electron configuration for magnesium is \begin{align*}1s^22s^22p^63s^2\end{align*}. The outer energy level for this atom is n = 3, and it has two electrons in this energy level. Therefore, magnesium has two valence electrons.
