Democritus and Leucippus (Greek philosophers

Everything that is perceived through the senses is made up of small, solid particles with different shapes and textures called atoms]]> 2020-10-02 19:19:16 UTC https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798905992 juanpa23a12 https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798912028 Dalton's atomic theory
John Dalton

Matter formed by atoms that are equal to each other, if they are of the same element and different from each other, if they are of different elements. They are neither created nor destroyed, they are preserved. The proportions of atoms are maintained when a compound is formed]]> 2020-10-02 19:21:43 UTC https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798912028 juanpa23a12 https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798918615 Existence of the electron
George Stoney/Joseph Thomson

The existence of other elementary charged particles, the electron, is proposed and then experimentally verified (cathode rays).]]> 2020-10-02 19:24:24 UTC https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798918615 juanpa23a12 https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798924406 Atomic model sultana pudding
Joseph Thomson

The atom is made up of a positive mass in which the negative electrons are embedded, like sultanas in a pudding, so that it is electrically neutral]]> 2020-10-02 19:26:08 UTC https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798924406 juanpa23a12 https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798931413 Nuclear atomic model (planetary model)
Ernest Rutherford

The atom has a central area, called the nucleus, which is positively charged, very small and solid where the mass of the atom is concentrated and a much larger and practically empty area around the nucleus called the periphery where the electrons that spin in orbits around the nucleus are located.]]> 2020-10-02 19:28:54 UTC https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798931413 juanpa23a12 https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798936755 Bohr atomic model (for Hydrogen atom)
Niels Bohr

The hydrogen atom consists of a central nucleus formed by a proton; around it the electron rotates in permitted circular orbits. The electron has defined values of energy. To each orbit corresponds a number that is related to the energy value]]> 2020-10-02 19:31:03 UTC https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798936755 juanpa23a12 https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798940106 Modelo de Schrödinger
Erwin Schrödinger and his group of researchers

Electrons behave as waves or particles arranged in orbitals of energy where there is some probability of finding them, and their energy is quantified and increases as the value of n increases, with n=1 being the lowest energy level.]]> 2020-10-02 19:32:27 UTC https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798940106 juanpa23a12 https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798952490 3 BGU]]> 2020-10-02 19:37:41 UTC https://padlet.com/juanpa23a12/e4zqes0n3988jry1/wish/798952490
