Question

Name the unit of energy used to express energy of atomic and subatomic particles.​

Answer 1

Answer:

An atomic mass unit, or amu, is one-twelfth of the mass of an unbound atom of carbon-12, and it used to express the mass of atomic and subatomic particles. The joule is the unit of energy in the International System of Units. Understanding of the relationship between the binding energy and the mass defect in Albert Einstein's Theory of Relativity equation clarifies the process of converting amu into joules. In the equation the mass defect is the “vanishing” mass of the protons and neutrons that is converted to energy that holds the nucleus together.
