Q. s – orbitals are nondirectional because of

A
Spherical symmetry
B
Their small size
C
Being first orbital
D
All of the above
Solution:

s orbitals are non – directional because they have spherical symmetry which means that the probability of finding an electron at a particular distance from the nucleus is same in all directions as compared with a p orbital . In any atom , the size of the s orbital increases as the principal quantum number of the orbital increases but its geometrical shape remains same .
