In the reaction given below A22286  B21084. How many α and β particles are emitted?

  • 6α, 3β

  • 3α, 4β

  • 4α, 3β

  • 3α,6β

Solution

B.

3α, 4β

A22284  B21084Decrease in mass number = 222 -210                                                = 12Number of α particles emitted                                                 =124                                               = 3 A22286  X21080  B21084

Increase in atomic number = 84 - 80 = 4

∴ Number of β particless emitted = 4
