Chapter 8, Problem 8.2P

Interpretation Introduction

Interpretation:

The criterion to arrange the elements in the periodic table is to be determined. Also, an example of a sequence of element order confirmed by Moseley’s findings is to be written.

Concept introduction:

Moseley studied the characteristics of the frequency of X rays that are emitted from the chemical elements. Moseley’s law states that the square root of the X-ray frequency is directly proportional to the atomic number of the element. This law considered atomic number more fundamental property than atomic mass.
