If you are talking about the electronic structure, which is 2.8.2. This would therefore mean that there are 2 electrons in the outer shell of magnesium.
There are 2 electrons in the first energy level, 8 electrons in the second energy level, and 2 electrons in the third energy level of a magnesium atom, as it has an atomic number of 12 with electron configuration 2-8-2.
A neutral atom of magnesium has 2 electrons in its outermost energy level. Magnesium has a total of 12 electrons, with 2 electrons in the first energy level and 8 electrons in the second energy level. The outermost energy level is the second energy level in the case of magnesium.
In magnesium, the third energy level can hold a maximum of 18 electrons. However, in a ground state magnesium atom, only 2 electrons are present in the third energy level, as magnesium has 12 electrons total - 2 in the first level and 8 in the second level.
The outermost electrons, found in the highest energy level, are the most likely to be lost in a magnesium atom. Magnesium has 2 electrons in its outermost energy level, so it tends to lose these electrons to achieve a stable electron configuration.
There are 2 electrons in the valence orbital of a Magnesium atom.
An example is magnesium.
In the second energy level of an atom, there can be a maximum of 8 electrons. Magnesium has 12 electrons in total, with 2 electrons in the first energy level and 8 electrons in the second energy level.
An atom with 12 electrons, such as a neutral magnesium atom, will contain 2 electrons in its first energy level, 8 electrons in its second energy level, and 2 electrons in its third energy level. The electron configuration table for magnesium would look like this: 1s2 2s2 2p6 3s2 For the atom of magnesium to become "stable," it would have to lose those two valence electrons in its outermost shell by forming an ionic bond with another atom, thus becoming a magnesium ion with a -2 charge, written as Mg-2.
There are 8 electrons in the third energy level of a calcium atom.
An atom of magnesium has 3 energy levels - the first energy level can hold up to 2 electrons, the second can hold up to 8 electrons, and the third can hold up to 18 electrons.
Neutral atom of magnesium has 12 electrons.
