What phase change is the reverse of condensation?

vaporization

Explanation: Condensation is a physical change involving phase transition from gaseous to liquid phase when energy is withdrawn.

Example of condensation:

Thus the reverse of condensation is a process where phase changes from liquid to gas.

Thus the reverse of condensation is vaporization where particles change from liquid to gaseous phase when energy is supplied.

Example of vaporization:

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
