उत्तर

Number of angular nodes for 4d orbital is 2.

Explanation:

The number of angular nodes is given by n – l 

Where n is principal quantum number, l is azimuthal quantum number

For 4d orbital, n = 4 and l = 2 

Thus, the number of angular nodes = n – l = 4 – 2 = 2

Which of the following statements concerning the quantum numbers are correct?

(i) Angular quantum number determines the three dimensional shape of the orbital.

(ii) The principal quantum number determines the orientation and energy of the orbital.

(iii) Magnetic quantum number determines the size of the orbital.

(iv) Spin quantum number of an electron determines the orientation of the spin of electron relative to the chosen axis.


The arrangement of orbitals on the basis of energy is based upon their (n + l) value. Lower the value of (n + l), lower is the energy. For orbitals having same values of (n + l), the orbital with lower value of n will have lower energy.

Based upon the above information, arrange the following orbitals in the increasing order of energy.

1s, 2s, 3s, 2p
