b.
Interpretation:The given orbital figure in part b. is to be labelled.
Concept Introduction:The shape of an orbital depends on the distribution of the electrons in free space.
b.

Answer to Problem 3RQ
The given orbital is s orbital.
Explanation of Solution
Due to the absence of any angular momentum, the electrons are evenly spread in their probable locations in all directions. When mapped, these locations give the orbital a spherical shape due to the even spread in all directions.
c.
Interpretation:The given orbital figure in part c. is to be labelled and identified.
Concept Introduction:The shape of an orbital depends on the distribution of the electrons in free space.
c.

Answer to Problem 3RQ
The given orbital is d orbital.
Explanation of Solution
d-orbitals are double dumbbell shaped due to their angular momentum number and spin number both being 2. Since both the numbers have value 2, the electrons’ movements in the three axes are restricted and on mapping the probable positions, the shape comes out to be somewhat flower-like arranged along the three axes of orientation.
