Chapter 8, Problem 8.2QP

Interpretation Introduction

Interpretation:

Moseley’s contribution to the modern periodic table should be discussed.

Concept Introduction:

Henry Moseley discovered that the frequency of X-rays generated by the element depends on its atomic number by bombarding high-energy electrons to an element.  According to him the properties of an element depend on their atomic number where atomic number is the total number of protons and electrons in an atom which help in the arrangement of elements in the modern periodic table.
