Question

Explain relevant physics concepts, such as atomic structure, radioactivity and x-rays by themselves and then what Marie Curie specifically contributed to.

Answer 1

Atmoc structure- atomic structure of an element tells about the Constitution of it's nucleus and the election around nucleus. Nucleus consist of positively charged protons and neutral neutrons. Negativily changed electrons revolves around nucleus.

Atoms of different elements have different atomic c structure.

Radioactivity - an unstable atoms stablised by emitting radiations. It is called radioactivity decay. Unstable atom emits energy in the form of alpha, beta and gamma radiations. Which results in stable atom.

X ray- When high speed electrons collided with metals then energy of elections converted in to X-rays.

Madam Marie Curie mainly contributed to the radiological decay of atom. She had studied radiation in uranium and other atoms which emit radiations.
