Find the total binding energy of the mass c = 12. u. nucleus (z =6), given the atomic a. 127.6 mev b. 104.6 mev c. 931.5 mev d. 92.2 mev e. 89.1 mev

The correct answer is Option D.

Explanation:

We are given a nucleus having representation:  

Number of protons = 6

Number of neutrons = 12 - 6 = 6

Number of electrons = 6

To calculate the mass defect of the nucleus, we use the equation:

where,

= number of protons  = 6

= mass of one proton  = 1.00728 u

= number of neutrons  = 6

= mass of one neutron = 1.00866 u

= number of electrons  = 6

= mass of one electron = 0.00054858 u

M = Mass number = 12

Putting values in above equation, we get:

To calculate the binding energy of the nucleus, we use the equation:

   (Conversion factor:    )

Hence, the correct answer is Option D.
