Question

Which atomic orbital is spherical in shape? (a) 2s (b) 3p (c) 3d (d) 4f​

Answer 1

Answer:

(a) 2s is the correct answer for this question.

Answer 2

Option (a) 2s  atomic orbital   is spherical in shape

Explanation:

(a) 2s atomic orbital is a spherical orbital.

• In the 2s orbital,  the probability of finding the electron is almost zero because there is a spherical shell around the nucleus.
• This spherical shell is known as a 'Node' or 'Nodal Surface'.
• 2s orbital will differ from its 1s orbital in having a nodal sphere within it.

(b) 3p atomic orbital is dumbbell-shaped.

It has nine orbitals in the n = 3 shell. In one orbital the 3s subshell and three orbitals are in the 3p subshell.

(c) 3d atomic orbital has a double dumb-bell shape.

There are five d orbitals dxy,dyz,dxz,dx2-y2,dz2 first three have double dumb-bell shapes. which lie in xy, yz and xz plane, respectively. The other two dx2-y2 ,dx2 is also dumb-bell shaped but lies along the x and y axes.

(d) 4f has a​  planar and conical nodes

It has two distinct shapes.
