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. 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).
8 electrons
If you are saying about L-shell then it has the capacity of 8 electrons. The l-shell consists of 2s and 2p orbitals which are capable of holding 2 and 6 electrons respectively.
The outer shell number for beryllium is 2. Beryllium has 4 electrons, so in its electron configuration, 2 electrons are in the first energy level and 2 electrons are in the second energy level, making the outer shell number 2.
In the second energy level, eight electrons are allowed at most.
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 second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
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.

For hydrogen (atomic number 1), there is 1 electron in the first energy level. For helium (atomic number 2), there are 2 electrons in the first energy level. For lithium (atomic number 3), there are 2 electrons in the first energy level and 1 electron in the second energy level. For beryllium (atomic number 4), there are 2 electrons in the first energy level and 2 electrons in the second energy level. For boron (atomic number 5), there are 2 electrons in the first energy level and 3 electrons in the second energy level.
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.

An atom with seven electrons will have five electrons in the second energy level.
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.
