Question
Chapter 25, Problem 57IAE
Interpretation Introduction
Interpretation:
The reason for the rounded off to not occur naturally in some cases needs to be explained.
Concept introduction:
Variants in a particular element when the number of neutrons and the number of nucleons differ they are known as isotopes.
The main characteristic of any given isotope is that the given elements differ in the number of neutrons in each atom but have the same number of protons.
Different atomic masses are seen in different isotopes.
