How many electrons are in the second energy level of magnesium?

There are 8 electrons in the second energy level of magnesium. This can be determined because magnesium has an atomic number of 12, meaning it has 12 electrons in total. The first energy level is filled with 2 electrons, leaving 10 electrons to distribute in the remaining energy levels, with 8 of those in the second level.


How many electrons are in the third energy level of oxygen?

There is no third energy level of oxygen, there is only two. The second energy level has 6 electrons.
