Question

Identify the type of change occurs in the following reaction:

${}_{11}^{23}Na{+}_1^{2}H⟶{}_{11}^{24}Na{+}_1^{1}H$

• A. Radioactive change
• B. Chemical Change
• C. Physical change
• D. None of these

Answer 1

Answer: (A)

Radioactive change

${}_{11}^{23}Na{+}_1^{2}H{⟶}_{11}^{24}Na{+}_1^{1}H$

It is a radioactive change as deuterium particles react with sodium nucleus and another isotope of Na & proton particles is formed.
