Question

Supply the missing species in each of the following nuclear equations. Replace the question marks with the appropriate integer or symbol.

Answer 1

Alpha \((\alpha)\) decay occurs when an unstable nucleus emits a particle composed of two protons and two neutrons.

Beta \((\beta)\) decay occurs when an unstable nucleus emists an electron.

In a nuclear equation, the sum of the atomic numbers on both the sides of a nuclear equation must be equal, and the sum of the mass numbers on both the sides must also be equal.

Thus, the balanced nuclear equations are as follows:

\(1 .{ }_{4}^{10} \mathrm{Be} \longrightarrow{ }_{5}^{10} \mathrm{~B}+{ }_{-1}^{0} e\)

\(2 .{ }_{14}^{34} \mathrm{Si} \longrightarrow{ }_{15}^{34} \mathrm{P}+{ }_{-1}^{0} e\)

3. \({ }_{78}^{192} \mathrm{Pt} \longrightarrow{ }_{76}^{188} \mathrm{OS}+{ }_{2}^{4} \alpha\)

\(4 .{ }_{12}^{2} \mathrm{Mg} \longrightarrow{ }_{13}^{28} \mathrm{Al}+{ }_{-1}^{0} e\)
