An electron is in a state with n=4. What are (a) the number of possible values of l, (b) the number of possible values of m_(l) , (c ) the number of poosible values of m_(s) , (d) the number of states in the n=4 shell, and (e) the number of subshells in the n=4 shell?

For a given value of n, the number of electrons in an orbit is

The position and energy of an electron is specified with the help of four quantum numbers namely, principal quantum number (n), azimuthal quantum number (l), magnetic quantum number (m_l) and spin quantum number (m_s) . The permissible values of these are : n = 1,2..... l = 0,1,.....(n-1) m_l = -l,......0,......+l m_s = +1/2 and -1/2 for each value of m_l . The angular momentum of electron is given as sqrt(l(l + 1)) cdot h/(2pi) While spin angular momentum is given as sqrt(s(s+1)) cdot (h/(2pi)) where s = 1/2 The electrons having the same value of n, l and m_l are said to belong to the same orbital. According to Pauli's exclusion principle, an orbital can have maximum of two electrons and these two must have opposite spin. Which of the following statements is not correct ?
