Answer 2

Nuclear energy :-

• A balanced nuclear equation is one where the sum of the mass numbers (the top number in notation) and the sum of the atomic numbers balance on either side of an equation.

• Nuclear equation problems will often be given such that one particle is missing.

• Instead of using the full equations, in many situations a compact notation is used to describe nuclear reactions.

A nucleus weighs less than its sum of nucleons, a quantity known as the mass defect, caused by release of energy when the nucleus formed.

Learning Objective

Calculate the mass defect and nuclear binding energy of an atom

Key Points

Nuclear binding energy is the energy required to split a nucleus of an atom into its components.

Nuclear binding energy is used to determine whether fission or fusion will be a favorable process.

The mass defect of a nucleus represents the mass of the energy binding the nucleus, and is the difference between the mass of a nucleus and the sum of the masses of the nucleons of which it is composed.

Binding Energy

Nuclear binding energy is the energy required to split a nucleus of an atom into its component parts: protons and neutrons, or, collectively, the nucleons. The binding energy of nuclei is always a positive number, since all nuclei require net energy to separate them into individual protons and neutrons.

Mass Defect

Nuclear binding energy accounts for a noticeable difference between the actual mass of an atom's nucleus and its expected mass based on the sum of the masses of its non-bound components.

Recall that energy (E) and mass (m) are related by the equation:

E = mc²
