1. When was Henry Moseley born?November 23, 1887
2. Where was Henry Moseley born?Weymouth, England
3. What is Henry Moseley known for?Established the concept of atomic number through X-ray spectroscopy
4. What is the formulated?Moseley's Law, relating X-ray frequency to atomic number (Z)
5. What is the potential recognition?Widely considered a likely recipient of the 1916 Nobel Prize in Physics
6. What did Henry Moseley discover about X-rays?Henry Moseley studied X-rays from elements and found that the wavelength of the X-rays changes in a predictable way that matches the element's place in the periodic table. This discovery became known as Moseley's Law.

X-ray Spectroscopy: The study of the interaction of X-rays with matter to determine elemental composition and structure.
Atomic Number (Z): The number of protons in the nucleus of an atom, defining its element.
Quantum Mechanics: A fundamental theory in physics describing nature at the smallest scales of energy and matter.
Nuclear Physics: The field of physics that studies atomic nuclei and the forces that hold them together.
