Who discovered the mass of an electron? Who developed the Standard Model of Particle Physics? Who discovered the mathematical equation for the nature of energy? Who discovered electrons? How has physical chemistry changed the world? Who discovered atomic mass?
Atomic Model: The atomic model was proposed in 1913. It proposes that atoms consist of a nucleus and electrons that orbit around it, much like how planets revolve around the sun in our solar system. Therefore, it is also sometimes referred to as the 'planetary model'. Answer and Explanation...

Helium is the second simplest atom when it comes to its atomic model, followinghydrogen. It consists of a nucleus of two protons and neutrons, and two electrons in atomic orbits. The most common form is helium-4, which is believed to be the product of Big Bang nucleosynthesis. This event...
