Orbital quantum numbers tell you what energy level the electron is in. In the Bohrmodel, this represents how high the orbit is above the nucleus; higher orbits have more energy. The first orbit is n=1, the second is n=2, and so on]]> 2017-10-04 17:58:28 UTC https://padlet.com/joshuahg023/31r2f5lz8wt6/wish/194013299 joshuahg023 https://padlet.com/joshuahg023/31r2f5lz8wt6/wish/194014232 His model suggested that atoms are the smallest particle of an element, that atoms of different elements have different masses, and that they are solid, indestructible units - much like a billiard ball. ]]> 2017-10-04 18:00:07 UTC https://padlet.com/joshuahg023/31r2f5lz8wt6/wish/194014232 joshuahg023 https://padlet.com/joshuahg023/31r2f5lz8wt6/wish/194023231 Dalton's model of the atom. John Dalton proposed that all matter is composed of very small things which he called atoms. This was not a completely new concept as the ancient Greeks (notably Democritus) had proposed that all matter is composed of small, indivisible (cannot be divided) objects.]]> 2017-10-04 18:14:37 UTC https://padlet.com/joshuahg023/31r2f5lz8wt6/wish/194023231 joshuahg023 https://padlet.com/joshuahg023/31r2f5lz8wt6/wish/194024541 Dalton's model of the atom.
