Question

how can the maximum number of electrons that can be accommodated in the outermost orbit is eight ????

Answer 1

heyy dear ur answer..........

However,  that the maximum number of electrons in the first orbital is 2, 8 in the second orbital, 8 in the third shell, 18 in the fourth orbital, 18 in the fifth orbital, 32 in the sixth orbital. I am fairly sure that orbitals and shells are the same thing........

hope this will help u...............@kundan

Answer 2

As per school level the maximum that can be accommodated in nth shell in given by
$2{n}^{2}$
But actually it is obtained solving for the stable configuration of an atom using spherical harmonics and schrodinger equation which i think is not needed at the moment
