The nucleus of oxygen atom contains 8 protons and 8 neutrons. What is the mass defect in amu?
[Given Mass of proton \(=1.00727\) amu Mass of neutron \(=1.00866 \mathrm{amu}\) and the mass of oxygen nucleus \(=15.99053 \mathrm{amu}\).]
- A 0.13691 amu
- B 0.12961 amu
- C 0.12691 amu
- D 0.13692 amu
Answer & Solution
Correct Answer
(A) 0.13691 amu
Step-by-step Solution
Detailed explanation
The mass defect \(\Delta m\) of a nucleus is defined as the difference between the sum of the masses of individual nucleons and the actual mass of the nucleus. The formula for mass defect is given by: \(\Delta m = [Z \times m_p + (A - Z) \times m_n] - M_{nucleus}\) Given: Number…
