Question

Based on which of the following Henry Moseley demonstrated characteristics of elements. a) X-Radiation decay b) B-Radiation decay c) y - Radiation decay d) None of the above​

Answer 1

Answer:

a x radiation decay he order the elements by this method

Answer 2

Henry Moseley demonstrated characteristics of elements using X-Radiation decay. (Option a)

• Henry Moseley's contribution to the field of atomic theory was through the discovery of Moseley's periodic table.
• Before his inventions, the atomic number was a mere number without any importance.
• Moseley was the first scientist to consider atomic numbers as a fundamental property in the classification of elements.
• He used X-ray decay to study different chemical elements.
• Through this, he discovered that atomic number and X-ray wavelengths were related and later this came to be known as Moseley's law.
