DONE

linear

tetrahedral

bent

trigonal bipyramidal

Explanation:

When there are two atoms around the central atom and no lone pair of electrons, the number of electron pairs will be 2  that means the hybridization will be sp and the electronic geometry of the molecule will be linear.

When there are four atoms around the central atom and no lone pair of electrons, the number of electron pairs will be 4  that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral.

When there are two atoms around the central atom and two lone pair of electrons, the number of electron pairs will be 4  that means the hybridization will be and the electronic geometry of the molecule will be bent.

When there are five atoms around the central atom and no lone pair of electrons, the number of electron pairs will be 5 that means the hybridization will be and the electronic geometry of the molecule will be trigonal bipyramidal.

true

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.
