Question 92: Atoms & Nuclei

Question

$$ 	ext { Match the following Columns. } $$

Column I
Column II

(A)
Nuclear fusion.
(P)
Converts some matter into energy.

(B)
Nuclear fission.
(Q)
Generally possible for nuclei with low atomic number.

(C)
$\beta$-decay.
(R)
Generally possible for nuclei with higher atomic number.

(D)
Exothermic nuclear reaction.
(S)
Essentially proceeds by weak nuclear forces.

Accepted Answer

In a nuclear fusion reaction, two or more lighter nuclei combine to give a comparatively heavier nucleus and some matter is converted into energy.
In a nuclear fission reaction, a heavy nuclear breaks into two or more lighter nuclei and some matter is converted into energy.
$\beta$-decay essentially proceeds by weak nuclear forces and converts some matter into energy. Exothermic nuclear reaction is possible for both type of nuclei (with low and high atomic number) and releases energy.

Answer

$$ [\mathrm{A} \rightarrow( \mathrm{Q}) ; \mathrm{B} \rightarrow(\mathrm{P}, \mathrm{R}) ; \mathrm{C} \rightarrow(\mathbf{P}, \mathbf{S}) ; \mathbf{D} \rightarrow( \mathbf{R})] $$

Answer

$$ [\mathrm{A} \rightarrow(\mathrm{P}) ; \mathrm{B} \rightarrow(\mathrm{P}, \mathrm{R}) ; \mathrm{C} \rightarrow(\mathbf{P}) ; \mathbf{D} \rightarrow(\mathbf{P}, \mathbf{Q}, \mathbf{R})] . $$

Answer

$$ [\mathrm{A} \rightarrow(\mathrm{P}, \mathrm{Q}) ; \mathrm{B} \rightarrow(\mathrm{P}, \mathrm{R}) ; \mathrm{C} \rightarrow(\mathbf{P}, \mathbf{S}) ; \mathbf{D} \rightarrow(\mathbf{P}, \mathbf{Q}, \mathbf{R})] . $$

Answer

$$ [\mathrm{A} \rightarrow(\mathrm{P}, \mathrm{Q}) ; \mathrm{B} \rightarrow(\mathrm{P}, \mathrm{R}) ; \mathrm{C} \rightarrow( \mathbf{S}) ; \mathbf{D} \rightarrow(\mathbf{P}, \mathbf{Q})] . $$
