Answer :
Mass defect is defined by the difference in the isotopic mass and the atomic mass. The mass defect in the nucleus of the nitrogen atom is 0.11235 amu.
What is a mass defect?
The mass defect has been the difference between the actual and the predicted atomic mass of the elemental atom. The predicted mass is calculated by simply adding the number of neutrons and the proton present inside the nucleus. The actual mass of the atom has been seen to be less than the predicted atomic mass of the atom.
Mass of neutral nitrogen atom = 14.003074 amu
It is already known that,
Mass of protons = 1.00728 amu
Mass of neutrons = 1.0086 amu
Mass of electron = 0.000549 amu
The given element ¹⁴N₇ contains seven electrons, protons, and neutrons in its structure. The mass defect is calculated as:
= (7 × 1.00728) - (7 × 1.0086) - (7 × 0.000549) - 14.003074
= 0.11235 amu
Therefore, the mass defect in nitrogen is 0.11235 amu.
