Why are atoms usually portrayed as spheres when most orbitals are not spherically shaped? a. The shape of an atom depends on the shape of its nucleus, not on the shape of its orbitals.
b. The shape of an atom depends on the shape of the outer orbital which always spherical
c. The shape of an atom is obtained by superimposing all of its orbitals.
d. The shape of an atom is not important so it is easier to treat atoms as spheres.

The shape of an atom is not important so it is easier to treat atoms as spheres.

Explanation:

In considering the shape of an atom, we do not consider the shape of the orbitals individually.

Hence, we do not seek to determine the exact shape of the atom, rather we simply treat the atom as spheres. Even though most orbitals are not spherically shaped.
