Using Bohr’s theory of hydrogen atom, obtain an expression for the radius of the $n^{\text{th}}$ orbit of an electron in an atom.
(b)[2.0]
Draw a labelled graph of binding energy of a nucleus per nucleon versus its mass number. Mark the region where nuclei are relatively more stable.
Draw: graph of binding energy of a nucleus per nucleon versus its mass number
Must show: binding energy per nucleon on vertical axis, mass number on horizontal axis, peak near iron-56, region of relatively more stable nuclei between mass numbers 30 and 170
