(1) The nucleus ⁷₃Li can emit an α–particle

(2) The nucleus of ²⁰⁶₈₂Pb can emit a proton 

(3) Deutron and alpha particle can undergo complete fusion 

(4) The nuclei ⁷⁰₃₀Zn and ⁸²₃₄Sn can undergo complete fusion

[Given; mass of = ¹₁H = 1.007825 u; ²₁H = 2.014102 u; ⁶₃Li = 6.01513 u; ⁷₃Li = 7.016004 u; ¹⁵²₆₄Gd = 151.919803 u ; ²⁰⁶₈₂Pb = 205.974455 u; ³₁H = 3.016050 u; ⁴₂He = 4.002603 u; ⁷⁰₃₀Zn = 69.925325 u; ⁸²₃₄Se = 81.919709 u; ²⁰⁵₈₁Be = 204.974454 u]

Answer 1

Correct option : (3) Deutron and alpha particle can undergo complete fusion

Explanation :

Two light nuclei, of mass m₁ and m₂, can undergo fusion, to produce a nucleus of mass M, if m₁ + m₂ > M

A heavy nucleus, of mass M₁, can break up into two nuclei of mass m₃ and m₄ , if
