Statement 1 The plot of atomic number ( Y -axis) versus number of neutrons ( x -axis) for stable nuclei shows a curvature towards X -axis from the line of 45^ slope as the atomic number is increased. Statement 2

Question

Quantrex Academy · Accepted Answer

Correct answer: A. Statement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.

The stability relationship can be represented by a line with a slope of

45^{\circ}

, i.e. the maximum stability is attained, when

N=Z

. Right or the curve a radioactive nuclide would be neutron rich and would decay be

\beta

-emission to produce a daughter nucleus with a lower

\frac{n}{p}

ratio. For heavier nuclides,

p-p

repulsions start to offset the attractive forces and an excess of neutrons over protons, is required for stability Statement 1 The plot of atomic number ( Y -axis) versus number of neutrons ( x -axis) for stable nuclei shows a
