Chapter 42: Q 24 Exercise (page 1236)

Identify the unknown isotope X in the following decays.
$a. X \to {}^{224}{Ra} + α b. {}^{35}S \to X + e^{-} + \bar{ν} c. X \to {}^{40}K + e^{+} + ν d. {}^{24}{Na} \to {}^{24}{Mg} + e^{-} + \bar{ν} \to X + γ$

Short Answer

Expert verified

Hence, the values of X is:

$a.) X = {}^{228}{Th} b.) X = {}^{207}{Tl} c.) X = {}^{7}{Li} d.) X = {}^{60}{Ni}$

Step by step solution

Given information

$a. X \to {}^{224}{Ra} + α b. {}^{35}S \to X + e^{-} + \bar{ν} c. X \to {}^{40}K + e^{+} + ν d. {}^{24}{Na} \to {}^{24}{Mg} + e^{-} + \bar{ν} \to X + γ$

Explanation (a)

In the following decays, we will find for the unknown isotope X:

$a.) X \to {}^{224}{Ra} + α$

The decay is:

$X = {}^{224}{Ra} + {}^{4}{He} X = {}^{228}{Th}$

Explanation (b)

The decay is:

Explanation (c)

The decay is:

Explanation (d)

The decay is:
