Answer 1

Answer:

Henry Moseley, in full Henry Gwyn Jeffreys Moseley, (born November 23, 1887, Weymouth, Dorset, England—died August 10, 1915, Gallipoli, Turkey), English physicist who experimentally demonstrated that the major properties of an element are determined by the atomic number, not by the atomic weight, and firmly established .

Answer 2

Henrey Moseley has presented the characteristics of elements in the option a) x-radiation decay.

Explanation:

• Henrey Moseley has presented the characteristics of given elements of atomic number.
• His experiments gathered that the frequencies of the X-rays have add on from an elemental target by the bombardment made by cathode rays were having characteristics of that element and can be able identify the charge on its atomic nucleus.
• According to him, same properties created periodically if the elements are arranged in order of ascending atomic numbers, there will be a periodic repetition of their chemical and physical properties.
