Question

The correct statement is

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

Answer 1

Answer: (C)

Deuteron and alpha particle can undergo complete fusion.

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.
