Nuclear Reaction

Level 2

Consider the two nuclear reaction formulas as follows: $\begin{aligned} [1]&: \quad _{1}^{2}\textrm{H}+_{1}^{3}\textrm{H} \to _{2}^{4}\textrm{He}+[A]+17.6 \text{MeV} \\ [2]&: \quad _{92}^{235}\textrm{U}+[B] \to _{56}^{141}\textrm{Ba}+_{36}^{92}\textrm{Kr}+3 _{0}^{1}\textrm{n}+200 \text{MeV} \end{aligned}$

Which of the following statements is correct about these nuclear reactions?

a) [1] is a nuclear fusion reaction.

b) [A] is an electron.

c) [B] has minus(-) electron charge.

a) 2 smaller atoms combined into 1 bigger atom is fusion regardless of particle(s) emitted; opposite to fission which splits.

b) No change of total number between protons and neutrons shall not release negative particle(s) such as electron(s) or $\beta$ -particle.

c) Let minus(-) electron = negative; no change of total number of protons and neutrons respectively should not release negative particle.

Answer: $\boxed{a)}$
