Electron repulsion is a fundamental force between two or more electrons within an atom or molecule that causes them to repel each other due to their negative charges.
Electron repulsion plays a major role in determining the electron configuration and bonding behavior of atoms and molecules. It causes electrons to occupy different energy levels and to form bonds with other atoms in order to minimize repulsive forces.
Electron repulsion is responsible for determining the shape and geometry of molecules. The repulsive forces between electrons cause them to arrange themselves in a way that minimizes their interactions, resulting in specific molecular shapes.
The strength of electron repulsion decreases as the distance between electrons increases. This is because the force of repulsion is inversely proportional to the square of the distance between two charges.
Electron repulsion can be observed in various phenomena, such as the repulsion between two negatively charged objects, the repulsion between electrons in a circuit, and the repulsion between valence electrons in chemical bonding. It also plays a role in determining the properties of materials, such as their conductivity and melting point.
