what is the difference between intermolecular forces and intramolecular forces
Intramolecular force An intramolecular force is any force that holds together the atoms making up a molecule or compound.[1] This includes all types of chemical bonds. They are usually stronger than intermolecular forces, which are present between atoms or molecules that are not bonded. Hydrogen bonds are an important example of a force that can be either intramolecular or intermolecular.
Nuclear force The nuclear force (or nucleon–nucleon interaction or residual strong force) is a force that acts between the protons and neutrons of atoms. Neutrons and protons, both nucleons, are affected by the nuclear force almost identically. Since protons have charge +1 e, they experience an electric force that tends to push them apart, but at short range the attractive nuclear force is strong enough to overcome the electromagnetic force. The nuclear force binds nucleons into atomic nuclei.
