The second energy level of atoms can hold a maximum of 8 electrons.
Maximum of 8 electrons in second energy level.
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.
The second energy level can hold a maximum of 8 electrons. Magnesium has 12 electrons, so in its second energy level, there will be 8 electrons (2 in the first energy level and 8 in the second energy level).
The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
An atom with seven electrons will have five electrons in the second energy level.

The first and second energy level will hold maximum of 2 and 8 electrons.
The maximum number of electrons in each energy level is determined by the formula 2n^2, where n represents the energy level (shell). For example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
8 electrons maximum
There could be a maximum of 8 electrons in the second energy level (n = 2)
