Answer 1

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

Step-by-step 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.
