Question

why s orbital are spherical in shape?​

Answer 1

Answer:

All s orbitals are spherical in shape and have spherical symmetry. This means that the wave function will depend only on the distance from the nucleus and not on the direction. In any atom, the size of the s orbital increases as the principal quantum number of the orbital increases but the geometry remains spherical.

Answer 2

Answer:

because it has zero angular momentum
