Chapter 2, Problem 2.22QP

Interpretation Introduction

Interpretation:

The incorrect isotopic symbols have to be identified.

Concept Introduction:

Isotopes: Isotopes are the atoms of the same element having same atomic number and different masses.  Thus, isotopes have same number of electrons and different number of electrons and different number of neutrons.

Examples:

Hydrogen atom has three isotopes namely, Hydrogen (${}_{\text{1}}^{\text{1}}\text{H}$) Deuterium (${}_{\text{1}}^2\text{H}$)

and Tritium (${}_{\text{1}}^3\text{H}$).
