The Nuclear Model Followed in early 1900's
Who came up with the Nuclear Model of the Atom and what is it?
Ernest Rutherford came up the the Nuclear Model in 1911. For the first time an atom was thought to contain small dense clumps of matter as well as a lot of empty space.
How did Mr. Rutherford come up with this model?
Good Question. He performed a famous experiment. He took foil and fired alpha particles at the foil sheet. Don't know what alpha particles are? Click Here! When he shot the alpha particles at foil, he measured the deflection of the particles when they emerged. He found that some of the alpha particles weren't deflected at all, while others were occasionally deflected at large angles. To his surprise, he saw that a few of the alpha bounced directly back. With this in mind, he could deduce that the foil wasn't made up of entirely empty space, but in some places, there were small dense clumps of matter in the foil. He realized that there must be something positively charged inside an atom. No other model had been invented with this data in mind. Believe it or not, Rutherford had discovered the nucleus.
What does the Nuclear model look like? I thought you'd never ask!
