An electron cannot have the quantum numbers n= 6 , l= 1 , m/= 0 . Option C.
Quantum numbers are the set of numbers used to describe the position and energy of an electron in an atom. There are four types of quantum numbers: principal, azimuthal, magnetic, and spin.
There are four quantum numbers in atoms: the principal quantum number (n), orbital angular momentum quantum number (l), magnetic quantum number (m), and electron spin quantum number(m). An electron with principal quantum number of 6 can only have angular momentum of 4 and above.
