Question

What is missing in the following nuclear reaction ${}_1{H}^2+{}_1{H}^2⟶{}_{2}H{e}^3+?$

• A. positron
• B. meson
• C. neutron
• D. electron

Answer 1

Answer: (C)

Given: Nuclear reaction: ${}_1{H}^2+{}_1{H}^2\to {}_{2}H{e}^3+?$.
We know that the balanced equation of the nuclear reaction is ${}_1{H}^2+{}_1{H}^2\to {}_{2}H{e}^3+{}_0{n}^1$. Where ${}_0{n}^1$ is the symbol of neutron.
Therefore neutron will be added in the given equation to complete it.
