The mass defect for the formation of oxygen-16 nucleus in g/mol and the binding energy in kJ/mol needs to be determined. Concept introduction: In an atom, three sub-atomic particles which are arranged in a certain way to make the atom stable. The nuclear attraction force works between electrons and protons due to opposite charges. The force between protons and neutrons holds these particles together. It can be measured by measuring the amount of energy necessary to break these forces. It can be calculated with the help of Einstein’s mass − energy equation: ΔE= m × c 2 The mass defect can be calculated as the difference in the atomic mass and the sum of masses of all atomic particles.

Interpretation:

The mass defect for the formation of oxygen-16 nucleus in g/mol and the binding energy in kJ/mol needs to be determined.

Concept introduction:

In an atom, three sub-atomic particles which are arranged in a certain way to make the atom stable. The nuclear attraction force works between electrons and protons due to opposite charges. The force between protons and neutrons holds these particles together. It can be measured by measuring the amount of energy necessary to break these forces.

It can be calculated with the help of Einstein’s mass − energy equation:

ΔE= m × c2

The mass defect can be calculated as the difference in the atomic mass and the sum of masses of all atomic particles.
