Niels Bohr- electrons have fixed distances and patterns of moving around nucleus’s r. Heisenberg-impossible to pinpoint electrons and their speed.

notes that i need for essay: 1) over 2400 years, the theory of atoms has changed 2) in 440 BCE democritus proposed that everything was made of small particles with space around them 2) he thought that the size varied depending on what they make 3) the word “atom” comes from the greek word “atomos” which meant indivisible 4) in 1808 some guy called john dalton showed that stuff broke down into different elements and proportions 5) he theorised that the compounds of elements were made of atoms that couldn’t be created or destroyed 6) in 1897 jj thompson discovered electrons using cathode rays 7) he then went on to create a “plum pudding model” for how the atom looked 8) by shooting alpha particles at a sheet of gold foil ernest rutherford discovered protons as some of the alpha particles were deflected from the gold 9) he concluded that atoms were mainly filled with empty space with a few electrons on the outside and a dense “nucleus” of protons 10) later james chadwick in 1932 discovered neutrons were in the nucleus 11) niels bohr thought that electrons went around the nucleus at fixed distances, but they could jump between the fixed distances 12) werner heisenberg concluded that you couldn’t determine the exact position and speed of an electron

Did you guys forget that Maharshi Kanada existed? Allow me to explain who he was, Maharshi Kanada was an Indian scientist, philosopher, and also a sage. One day, he was walking with food on his hand, as he ate the food, after chewing for a while, it occured to him that he couldn’t divide the food into further parts, and thus, the idea of a matter which cannot be divided further came into existence. He called that invisible matter “Anu”, a sanskrit word which now we use for atoms. Don’t try and say “Oh, he probably was a person from after the 18th century or some time in the modern age.”, well to that, I shall say NOPE! Kanada was born somewhere around the 6-4th century BCE. I can’t tell if he discovered it first or not, because if Kanada was born on the 6th century BCE, it would make him the person who theorized the idea first, but if he was born around the 4th century BCE, that would make me more confused since Democritus lived from c. 460-370 BC. Also, fun fact, the reason why Democritus was given the credit more than Kanada did was because he made the concept more popular, because some people embraced the idea of atomism in the ancient Greeks, and unpopular, because some philosophers, like Plato and Aristotle, disagreed with the idea. I forgot to mention that Leucippus (the teacher of Democritus), Dharmakirti, Parmenides, and many more atomists existed in the ancient times, middle ages, and the 17th century, so really, atomism was not “lost until the 18th century.” Great, history is now making my head hurt.

[@johnhopkins6260]

It's been 40 years since high school; is the "wobble" of electrons in orbit affected/caused by the variations in electrical charge/attraction of the spinning nucleus (momentarily attracted to protons, momentarily not by neutrons)? Similarly, do the orbital "dips" of the electron perpetuate nucleus spin? Understanding that like charges repel, What keeps the protons & neutrons "glued" together in the nucleus? (gravity?) With Protons ("pro"=positive), Neutrons (=neutral) and electrons, were it not more apropos to refer to electrons as "Negtrons"? Or, as understood as "transporters" of so-called electricity, "electron" should prevail? (to "cover" the initial misunderstanding that electrons were positively charged... as Newton's apple was "positively charged); "current flow" vs. "electron flow".

I'm kind of put down that the Mu'tazilites were overlooked in this presentation. Their idea of atomism, proposed by Dirar ibn 'Amr and Abu al-Hudhayl of the Basra school proposed the idea that every thing was made up of an enormous amount mathematical points. It was also postulated in response by the same school than atoms were less mathematical points but more the concept that a physical body can be divided up infinitely, if perhaps into its parts and the parts of its parts and so on.
