QUESTION 1 6.36364 points Save Answer what is the approximate radius of the nucleus of the 147N atom? 1.7 X 10-14m b.4.5 X10 1 m 2.9x1015 m Od3.3x1012 m e. 1.2 x 10 15 m O a. 15 QUESTION 2 6.36364 points Save Answer The mass of the 147N atom, including its eight electrons, is 14.003074 u. The mass of the 11H atom, including its one electron, is 1.007825 u. The mass of a neutron is 1.008665 u. What is the binding energy of the nucleus of the 147N atom? a. 14.0 Mev b. 0.112 Mev c. 1.87 Mev Od. 12.0 Mev Oe. 105 MeV

Explanation / Answer

(1)
Radius of the Approximate nucleus is given by,
R = A^(1/3) * (1.20 * 10-15)
R =  14^(1/3) * (1.20 * 10-15)
R = 2.9 * 10^-15 m
Correct option - (c)

(2)

Binding Energy = [ 7 * (1.007825 u) + 7 * (1.008665 u) - 14.003074 u ] c^2 *(931.5 Mev / c^2*u)
Binding Energy = 104.7 Mev

Correct option - (e)

(3)
Binding Energy per nucleon = Total Bnding Energy / 14
Binding Energy per nucleon = 104.7 Mev / 14
Binding Energy per nucleon = 7.48 Mev
Correct option - (d)

(4)
An alpha particle consists of two protons and two neutrons. The symbol for an particle is 2He4.
84Po210 --> 2He4 + 82Pb206
After alpha decay, Daughter nucleus produced is , 206PB82.

Correct option - (b)
