Nuclear Decay

List I

List II

(A) Rn₂₂₂⁸⁶ → Po₂₁₈⁸⁴

(III) α particle

(B) Bi₂₁₄⁸³ → Po₂₁₄⁸⁴

(I) β− particle

(D) Na₂₂¹¹ → Na₂₂¹⁰

(II) β+ particle

- A:

%5E%7B222%7D_%7B86%7DRn%20%5Cto%20%5E%7B218%7D_%7B84%7DPo

undergoes alpha decay, emitting a

%5Calpha

-particle, so the correct match is

%5Ctext%7BA-II%7D

. - B:

%5E%7B214%7D_%7B83%7DBi%20%5Cto%20%5E%7B214%7D_%7B84%7DPo

undergoes beta decay, emitting a

%5Cbeta

-particle, so the correct match is

%5Ctext%7BB-I%7D

. - C:

%5E%7B234%7D_%7B90%7DTh%20%5Cto%20%5E%7B234%7D_%7B92%7DU

undergoes alpha decay, emitting a

%5Calpha

-particle, so the correct match is

%5Ctext%7BC-IV%7D

. - D:

%5E%7B22%7D_%7B11%7DNa%20%5Cto%20%5E%7B22%7D_%7B10%7DNa

undergoes beta decay, emitting a

%5Cbeta

-particle, so the correct match is

%5Ctext%7BD-III%7D

. Thus, the correct matching is: A-II, B-I, C-IV, D-III.
