Answer

Explanation:

Step1: Recall nuclear - equation balance rules

In a balanced nuclear equation, the sum of mass numbers (top numbers) and the sum of atomic numbers (bottom numbers) must be equal on both sides of the equation.

Step2: Analyze the first option

For $\ce{^{23}{11}Na}\rightarrow\ce{^{24}{12}Mg}+\ce{^{1}_{1}H}$, mass number on left is 23, on right is $24 + 1=25$. Atomic number on left is 11, on right is $12+1 = 13$. Not balanced.

Step3: Analyze the second option

For $\ce{^{24}{11}Na}\rightarrow\ce{^{24}{12}Mg}+\ce{^{0}_{ - 1}e}$, mass number on left is 24, on right is $24+0 = 24$. Atomic number on left is 11, on right is $12+( - 1)=11$. Balanced.

Step4: Analyze the third option

For $\ce{^{24}{13}Al}\rightarrow\ce{^{24}{12}Mg}+\ce{^{0}_{ - 1}e}$, mass number on left is 24, on right is $24 + 0=24$. Atomic number on left is 13, on right is $12+( - 1)=11$. Not balanced.

Step5: Analyze the fourth option

For $\ce{^{23}{12}Mg}\rightarrow\ce{^{24}{12}Mg}+\ce{^{1}_{0}n}$, mass number on left is 23, on right is $24+1 = 25$. Atomic number on left is 12, on right is $12 + 0=12$. Not balanced.

Answer:

$\ce{^{24}{11}Na}\rightarrow\ce{^{24}{12}Mg}+\ce{^{0}_{ - 1}e}$
