Chapter 4, Problem 64A

Interpretation Introduction

Interpretation:

Whether $\text{M}\text{g}$, $\text{M}\text{g}$, $\text{M}\text{g}$ are isotopes of each other or not needs to be explained.

Concept introduction:

Isotopes of an element have same atomic number and different mass number.

Answer to Problem 64A

Yes, $\text{M}\text{g}$, $\text{M}\text{g}$, $\text{M}\text{g}$ are isotopes of each other as all three have same atomic number and different mass number

Explanation of Solution

The atomic symbol is represented as follows:

$\text{X}$

$\begin{array}{l}\text{A = Mass number }\hfill \\ \text{Z = Atomic number }\hfill \end{array}$

The given species are as follows:

$\text{M}\text{g}$, $\text{M}\text{g}$, $\text{M}\text{g}$

Here, all three have same atomic number i.e. 12 with different mass number

$\therefore$ All three are isotopes of each other.

Conclusion

Atoms of element with similar Atomic number and different Mass number are isotopes of each other
