Question

Which of the following statements are CORRECT ?

(I) A large number of orbitals are possible in an atom.

(II) Qualitatively these orbitals can be distinguished by their size, shape and orientation

(III) An orbital of smaller size means there is more probability of finding the electron near the nucleus

(IV) Each orbital is designated by four quantum numbers

Answer:

D

Solution:

Orbitals differ in size, shape, orientation and many exist.
Smaller orbital ⇒ electron closer to nucleus.
Orbital needs 3 quantum numbers (not 4).
