Write the significance of a plus $(+)$ and a minus $(-)$ sign shown in representing the orbitals.

(N/A) The plus $(+)$ and minus $(-)$ signs in orbital representations correspond to the phase of the electron wave function $(\psi)$. Their significance includes:
$(i)$ Determining whether constructive or destructive interference (overlapping) occurs between orbitals.
$(ii)$ Indicating whether the energy of the system increases (repulsion) or decreases (attraction) upon interaction.
$(iii)$ Predicting whether a chemical bond will form or not.
$(iv)$ Providing information regarding bond formation,molecular geometry,and bond angles.
