Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom.
Torque has the dimension of force times distance, symbolically L2MT−2. Official SI literature suggests using the unit newton metre (N⋅m), or, joule per radian (J/rad). The unit newton metre is properly denoted N⋅m rather than m.
