Chapter 14, Problem 14.15PAE

(a)

Interpretation Introduction

To determine:

The process of transformation of T230h to R226a

(a)

Expert Solution
Check Mark

Explanation of Solution

Atomic numbers of thorium and radium are 90 and 88, respectively.

Consider the transformation:

T90230hR88226a

Thus, balancing the atomic number on both sides, we get that unknown particle ejected has atomic number of 9088=2 and the atomic mass as 230226=4. The nucleus with atomic number 2 and mass number 4 is aHelium nucleus. Hence, the process leading to the transformation of T230h to R226a is an alpha emission process.

(b)

Interpretation Introduction

To determine:

The process of transformation of C137s to B137a

(b)

Expert Solution
Check Mark

Explanation of Solution

Atomic numbers of Cs and Ba are 55 and 56, respectively.

Consider the transformation:

C55137sB56137a

Thus, balancing the atomic number on both sides, we get that unknown particle ejected has atomic number of 5556=1 and the atomic mass as 137137=0. The particle with atomic number -1 and mass number 0 is an electron. Hence, the process leading to the transformation of C137s to B137a is a beta emission process.

(c)

Interpretation Introduction

To determine:

The process of transformation of K38 to A38r

(c)

Expert Solution
Check Mark

Explanation of Solution

Atomic numbers of K and Ar are 19 and 18, respectively.

Consider the transformation:

K1938A1838r

Thus, balancing the atomic number on both sides, we get that unknown particle ejected has atomic number of 1918=1 and the atomic mass as 3838=0. The particle with atomic number 1 and mass number 0 is a positron. Hence, the process leading to the transformation of K38 to A38r is a positron emission process.

(d)

Interpretation Introduction

To determine:

The process of transformation of Z97r to N97b

(d)

Expert Solution
Check Mark

Explanation of Solution

Atomic numbers of Zr and Nb are 40 and 41, respectively.

Consider the transformation:

Z4097rN4197b

Thus, balancing the atomic number on both sides, we get that the unknown particle ejected has atomic number of 4041=1 and the atomic mass as 9797=0. The particle with atomic number -1 and mass number 0 is an electron. Hence, the process leading to the transformation of Z97r to N97b is a beta emission process.

K1938A1838r+β10+ν

Conclusion

Therefore, if one of the species from the radioactive decay equation is missing, it can be determined by balancing atomic numbers and atomic mass numbers. Thus, the type of radioactive decay process can be determined if the atomic mass and atomic number of transforming nuclei is given.
