Chapter 4: Q. 4.43 (page 115)

There are two naturally occurring isotopes of thallium: T81203Iand T81205I. Use the atomic mass of thallium listed on the periodic table to identify the more abundant isotope.

Short Answer

Expert verified

T81205I is more abundant isotope of thallium.

Step by step solution

01

Given information.

We have been given that,

T81203I,T81205I

We need to find which isotope is more abundant in nature.

02

Simplify.

T81205I is more abundant isotope of thallium as it comprises 70%atomic mass of thallium whereas T81203Iisotope comprises only 30%of the atomic mass .
