Question 1 Report

The energy required to separate the nucleus in an atom completely is known as

Answer Details
The correct answer is "nuclear binding energy". The energy required to separate the nucleus in an atom completely is called the nuclear binding energy. It is the energy needed to overcome the strong force, which is the force that holds the nucleus together. This energy is released when the nucleus is formed, and it is also released in nuclear reactions such as fusion and fission. The other options listed, mass defect of the atom, electron binding energy, and excitation energy, are all different concepts that are not directly related to the energy required to completely separate a nucleus.
