how many electrons can be contained in all orbitals with n=4??????

Max number electrons = 2N^2

thanks...andy

so 2 X4 ^2 = 32

so 32 is correct .......
thanks andy

right

thanks so much ...andy

To determine the maximum number of electrons that can be contained in all orbitals with a given principal quantum number (n), you can use the formula 2n². For n = 4, the calculation would be:

2(4)² = 2(16) = 32

Therefore, the maximum number of electrons that can be contained in all orbitals with n = 4 is 32 electrons.
