8
The maximum number of electrons in the second energy level of an atom is 8.
The second energy level can hold a maximum of 8 electrons. This is based on the formula 2n^2, where n is the principal quantum number representing the 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 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.
The second energy level of atoms can hold a maximum of 8 electrons.
The maximum number of electrons in the second principle energy level (n=2) is 8. This can be determined from 2(n^2) which for n=2 would be 2 x 4 = 8. It can also be seen by writing the electron configuration for n=2 which would be 2s2 2p6 for a total of 8 electrons.
An element with two energy levels can have a maximum of 8 electrons. The first energy level can hold up to 2 electrons, while the second energy level can hold up to 6 electrons.
The maximum number is 8 electrons in the second shell.
