Question

The four isotopes of lead and its abundances are:

Pb-204: 1.37

Pb-206: 24.10

Pb-207: 22.10

Pb-208: 52.40

Which isotope is the most abundant?

A. Pb-204

B. Pb-206

C. Pb-207

D. Pb-208

Answer 1

The isotope of lead that is the most abundant is Pb-208, with an abundance of 52.40%.

Step-by-step explanation:

You asked which isotope of lead is the most abundant. By looking at the given abundances of the four isotopes of lead, you can determine this directly. The abundances are as follows: Pb-204: 1.37%, Pb-206: 24.10%, Pb-207: 22.10%, and Pb-208: 52.40%. Comparing these percentages, it's clear that Pb-208 is the most abundant isotope of lead, as it has the highest abundance value of 52.40%.
