Question

Write the significance of a plus and a minus sign shown in representing the orbitals.

Answer 1

The orbital is the highest possibility of getting a particle around the hub.

This expectation is measured regarding the wave function.

The wave function can beget either positive or negative values.

For defining the wave function, plus sign is followed for positive wave function while a minus sign is done for the unenthusiastic wave function of an orbital.

Answer 2

Explanation:

Generally, the plus sign represents the crest of the electron wave and the minus sign represents the troughs of the electron wave.
