Question

The correct statement is

• A. The nucleus ${}_3^{6}Li$ can emit an alpha particle
• B. Deuteron and alpha particle can undergo complete fusion.
• C. The nucleus ${}_{84}^{210}Po$ can emit a proton.
• D. The nuclei ${}_{30}^{70}Zn$ and ${}_{34}^{82}Se$ can undergo complete fusion.

Answer 1

Answer: (B)

For fusion reaction to take place, sum of masses of lighter nuclei must be greater than mass of heavy nucleus formed.

For fusion reaction : ${}_1^{2}H{+}_2^{4}He{\to }_3^{6}Li$

Sum of mass of lighter nuclei $M_l=2.014102+4.002603=6.016705$ u

Mass of ${}_3^{6}Li$ $M_h=6.015123$ u

As $M_l>M_h$, thus above reaction is possible.
