Chapter 42: Q 25 Exercise (page 1236)

Identify the unknown isotope X in the following decays.
$a. {}^{230}{Th} \to X + α b. {}^{35}S \to X + e^{-} + \bar{ν} c. X \to {}^{40}K + e^{+} + ν d. {}^{24}{Na} \to {}^{24}{Mg} + e^{-} + \bar{ν} \to X + γ$

Short Answer

Expert verified

Hence, the values of X are:

$a.) X = {}^{226}{Ra} b.) X = {}^{35}{Cl} c.) X = {}^{40}{Ca} d.) X = {}^{24}{Mg}$

Step by step solution

Given information

$a. {}^{230}{Th} \to X + α b. {}^{35}S \to X + e^{-} + \bar{ν} c. X \to {}^{40}K + e^{+} + ν d. {}^{24}{Na} \to {}^{24}{Mg} + e^{-} + \bar{ν} \to X + γ$

Explanation (a)

In the following decays, we need find unknown isotope X:

$a.) {}^{230}{Th} \to X + α$

The decay is:

${}^{230}{Th} = X + {}^{4}{He} X = {}^{226}{Ra}$

Explanation (b)

The decay is:

Explanation (c)

The decay is:

Explanation (d)

The decay is:
