The molecular shape or molecular geometry of electron pair repulsion is determined by the no of electron pair present.
The lightest known stable subatomic particle is the electron. It has an equal negative charge to that of 1.602176634 coulombs, which is regarded as the fundamental unit of electric charge. Only 1/1,836 of a proton's mass, or 9.1093837015 1031 kg, is present in the rest mass of the electron.
As a result, compared to a proton or neutron, an electron is thought to be almost massless, and its matter is not taken into account when determining an atom's mass number.
The quantity of electron pairs in a molecule affects its form. Electron pair interactions are typically repulsive. Electron couples align themselves to reduce their attraction to one another. It is assumed that the valence, or outermost, electron shell, is spherical
Therefore, the molecular shape or molecular geometry of electron pair repulsion is determined by the no of electron pair present.
