The element with atomic number 84 and mass number 218 change to other element with atomic number 84 and mass number 214. The number of `alpha` and `beta` particles emitted are respectively.

Text Solution

Verified by Experts

`""_(84)X^(218) overset( alpha "decay") to ""_(82)Y^(214)+ x""_(2)He^(4)`
`""_(82)Y^(214) overset(2beta) to ""_(84)Y^(214)+y""_(2)e^(0)`
Number of alpha decay, X = 1
Number of beta decay, y = 2
