![]() ![]() Ive already told you, for instance about the French chemist Antoine Lavoisier who proposed the Law of Conservation of Mass which states that even if matter changes in shape or form, its mass stays the same. I proposed an improved atomic model which involved the electrons move in definite orbit around the nucleus, almost like the solar system!. The next major developments in atomic theory didnt come along for nearly 2,300 years. I say that atoms are indeed positively charged through something in the center that I like to call the nucleus. sorry to bust your bubble there Thompson. I came up with atoms that are indeed not plum puddings. This goal supports Virginia SOL PS.2 The student will investigate and understand that matter is composed of atoms. While we are on a role here let me introduce myself. The students will place the historical contribution of each Atomic Theory scientist into an atomic theory timeline, place the correct model of the atom with each scientist, and list the characteristics of each model. I proposed a model called them plum pudding, think of it like a cookie.I was hungry okay I ,yes I, provided the first hint that atoms are made of even smaller particles known as the electron. But anyway, I came up with the theory that all matter is made of atoms and that they are too small to see which ofc would make them uncuttable and indestructible. I performed the first atomic theory since the death of chemistry sponsored by my good guy Aristotle haha. my model was also the death of the field chemistry for 2000 years. I also believe that matter only consist of hot, dry, cold, wet. i believe that all matter is made up of 4 elements fire, air, water, earth. ![]() He described particles as tiny hard, uncuttable ( lego like ) He named the smallest piece of matter atom ( meaning not to be cut ). Discovered that the matter was small indivisible. I even named my first smallest piece of matter atomsĪbout 300 B.C Democritus begun research on matter. There is a never-ending amount of atoms in the universe, all in varying shapes and sizes. if you didn't know I was the one who begun the research matter, called them indivisible actually. Philosopher (460 BCE-370 BC) Democritus atomic theory adhered to the following principles: - Everything is made up of atoms. ![]()
