There are six electrons are in the second energy level of magneisum. A further two are on the first energy level and the last two are on the third energy level.
2 electrons. Magnesium has 12 total, in 3 shells, 2,8,2There are two electrons in magnesium's third energy level.
A neutral atom of magnesiumhas two electronsin its outermost energy level
Calcium atoms have 8 electrons in the second energy level. However, they are not the valence electrons. The outermost electrons in a calcium atom in the ground state are 2 4s electrons. So calcium atoms in the ground state have 2 valence electrons in the fourth energy level.
well, on the periodic table of elements a chlorine atom has 17 electrons, usually the first level holds up to two electrons and the second level holds up to 8. so if my figuring is correct there should be fifteen electrons on the second energy level.

2 electrons. Magnesium has 12 total, in 3 shells, 2,8,2There are two electrons in magnesium's third energy level.
2 electrons are in magnesiums last energy level
An atom of magnesium has two valence electron. It can have a full outer level by losing two electron. The second energy level becomes the outermost energy level with eight electrons.
Magnesium is 1s22s22p63s2 and so the 3rd energy level is the highest occupied level.
All elements except hydrogen have two electrons in the first energy level.

Magnesium (Mg) has two electrons in it's lowest (s) orbital.
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
An atom with seven electrons will have five electrons in the second energy level.
More energy have the electrons in the second level of energy.
An example is magnesium.
