    The principal quantum number of n of an atomic orbitals is 5 what are the posible values of l ?

    An electron having the quantum numbers n=4, l=3 , m=0 , s=-1/2 would be in the orbital

    Orbital is the region in an atom where the probability of finding the electron around the nucleus. Orbitals do not specify a definite path according to the uncertainty principle. An orbital is described with the help of wave function Phi . Whenever an electron is described by a wave function, we say that an electron occupies that orbital. Since, many wave functions are possible for an electron, there are many atomic orbitals in an atom. Orbitals have different shapes, except s-orbitals, all other orbitals hae different shapes, except s-orbitals, all other orbital have different shapes, except s-orbitals, all other orbitals have directional character. Number of spherical nodes in an orbital is equal to (n-l-1) . Orbital angular momentum of an electron is sqrt(l(l+1))h . Q.
