What is the birthdate of this English physicist, who published first the Long Form periodic table or Modern periodic table and published Moseley's Law?
Henry Moseley Henry Gwyn Jeffreys Moseley (23 November 1887 – 10 August 1915) was an English physicist, whose contribution to the science of physics was the justification from physical laws of the previous empirical and chemical concept of the atomic number. This stemmed from his development of Moseley's law in X-ray spectra. Moseley's Law justified many concepts in chemistry by sorting the chemical elements of the periodic table of the elements in a logical order based on their physics. He published first the Long Form periodic table or Modern periodic table which is used till date.
Alice Leigh-Smith Alice Leigh-Smith (née Prebil) was an English nuclear physicist. She married Philip Leigh-Smith, the son of the Arctic explorer Benjamin Leigh-Smith, in 1933. She was a student of Marie Curie and was the first British woman to receive a PhD in nuclear physics. She, together with Walter Minder, announced the discovery of element 85 (now called astatine) in 1942. They proposed the name anglohelvetium for the new element. Later it was proven that in fact Walter Minder had not discovered element 85. Leigh-Smith was also involved in the use of radioactive substances as a treatment for cancer.
