Question

Which one of the following reactions is nuclear fusion? (a) ^226_88 RA rightarrow ^222_86 Ra + ^4_2 He (b) P^+ + e^- rightarrow ^1_1 H (c) ^2_1 D + ^2_1 D rightarrow ^3 He + n^0 (d) ^235_92 U rightarrow ^140_54 Xe + ^94_38 Sr + n^0 ^22_11 Na rightarrow ^22_10 Ne + e^+ + v_e Which one of the following reactions is beta -decay? (a) ^1_1 H rightarrow P^+ + e^- (b) n^0 rightarrow P^+ + e^- + v^-_e (c) 2 H_2O + O_2 rightarrow 2 H_2O (d) ^235_92 U rightarrow ^140_54Xe + ^94_38 Sr + n^0 (e) ^3_2 He + ^3_2 HE rightarrow ^4_2 He + 2 p^+

Explanation / Answer

1) In nuclear fusion, lighter nuclei combine to form a heavier nucleus. So, reaction (c) is nuclear fusion reaction.

2) In beta minus decay, a neutron is converted to a proton and the process creates an electon and an antineutrino. So, reaction (b) is beta minus decay reaction.
