Question

Complete each nuclear fusion reaction.

Answer 1

Answer: D represents 222, E represents 86, F represents 234 and G represents 90.

Explanation:

The two given chemical reactions are a type of alpha decay processes. Alpha decay process is defined as the process, in which a heavier nuclei decays into lighter nuclei emitting alpha particle. The alpha particle released has a charge of +2 units. and is also known as a helium nucleus.

$_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}\textrm{Y}+_2^4\textrm{He}$

The isotope formed has atomic mass reduced by 4 units and atomic number reduced by 2 units.

So, for the chemical equations:

1. $_{226}^{86}\textrm{Ra}\rightarrow _{222}^{84}\textrm{Rn}+_2^4\textrm{He}$

D represents 222, E represents 86.

2. $_{238}^{92}\textrm{U}\rightarrow _{234}^{90}\textrm{Rn}+_2^4\textrm{He}$

F represents 234 and G represents 90.

Answer 2

Answer:

D 222, E 86, F 234 and G 90.
