Complete each nuclear fusion reaction. 226 88 ra → d e rn + 4 2 he d: e: 238 92 u → f g th + 4 2 he a: b: c: d: e:

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

Explanation:

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.

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

So, for the chemical equations:

1.

D represents 222, E represents 86.

2.

F represents 234 and G represents 90.
