8 electrons maximum
The maximum number of electrons that can be accommodated in the fourth principal energy level (n=4) is 32. This is because the formula 2n^2 gives the maximum number of electrons that can occupy a particular energy level. So, for n=4, the maximum number of electrons is 2 * 4^2 = 32.

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.
D has 5 orbitals and can be filled with up to 10 electrons.
The principal energy level is represented by the main energy level number (n). The valence electrons are the electrons found in the outermost energy level of an atom, which corresponds to the highest principal energy level (n).
The maximum number of electrons in an energy level (and I assume you mean energy shell- with a principal quantum number) is 2n2 where n is the princiapl quantum number This gives the numebr per level of 2, 8, 18, 32, 50
The fourth outer energy level of an atom can contain a maximum of 32 electrons. This is because each energy level can hold a maximum of 2n^2 electrons, where n is the principal quantum number of the energy level. In this case, the fourth energy level has a principal quantum number of 4, so it can hold 2(4^2) = 32 electrons.
The maximum number of electrons with principal quantum number 4 and angular momentum quantum number 0 would be 2 electrons. This is because for each energy level (n), there can only be one orbital (l=0) present, and each orbital can hold a maximum of 2 electrons (with opposite spins, as per the Pauli exclusion principle).
