Find out the total number of alpha and ...

Find out the total number of `alpha` and `beta-` particles in the following disintegration:
`._(90)Th^(228) rarr ._(83)Bi^(212)`

Text Solution

Verified by Experts

The correct Answer is:
`5`
`._(92)Th^(238) overset(-4alpha)(rarr) ._(82)X^(212) overset(-1beta)(rarr) ._(83)Bi^(212)`
Total no of `alpha-` and `beta-` particles `= 4+1 = 5`
