Niels Bohr proposed a model of the atom in which the electron was able to occupy only certain orbits around the nucleus. This atomic model was the first to use quantum theory, in that the electrons were limited to specific orbits around the nucleus.]]> 2021-11-02 05:02:39 UTC https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1860691919 Quantum Mechanical Model ashleyconstantino https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1860693212 According to the quantum mechanical model of the atom, a nucleus is surrounded by an electron cloud.

Democritus was a Greek philosopher who lived between 470-380 B.C. Democritus introduced the idea of the atom as the basic building block matter. He thought that atoms are tiny, uncuttable, solid particles that are surrounded by empty space and constantly moving at random. Democritus believed that everything in the universe was made up of atoms, which were microscopic and indestructible. ]]> 2021-11-11 00:17:14 UTC https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1882701782 John Dalton ( 1800's ) - Katherine Cabrera ashleyconstantino https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1882704716 John Dalton was an english chemist, meteorologist and physicist. 
He is known for introducing the atomic theory in chemistry. He
Is also the first to study color blindness. His atomic model, solid sphere
model in 1803, states that all objects are made or composed of
Atoms, that they are a solid that cannot be divided or broken down
Into pieces. As a result of his gas study, he came up with this idea; 
Gases could only be combined in specific proportions.]]> 2021-11-11 00:18:53 UTC https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1882704716 Ernest Rutherford ( 1909 ) - Ashley Kaye Constantino ashleyconstantino https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883359028 The Rutherford model was devised by the New Zealand-born physicist Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson's plum pudding model of the atom was incorrect. Rutherford's new model for the atom, based on the experimental results, contained new features of a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume also containing the bulk of the atomic mass of the atom. This region would be known as the "nucleus" of the atom.]]> 2021-11-11 05:35:49 UTC https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883359028 Atomic de Broglie model ashleyconstantino https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883363118 The de Broglie atomic model was proposed by the French physicist Louis Broglie in 1924. In his doctoral thesis, Broglie asserted the wave-particle duality of electrons, laying the foundations for wave mechanics. Broglie published important theoretical findings on the wave-corpuscle nature of matter at the atomic scale.
Later, de Broglie statements were experimentally demonstrated by scientists Clinton Davisson and Lester Germer in 1927. De Broglie’s electron wave theory is based on Einstein’s proposal on the wave properties of light at short wavelengths.

The electron cloud refers to a region outside the nucleus where an electron is most likely to be found.

Before understanding what an electron cloud model is, it is important to know about the forces that bind the electrons together. You might also like to know about the parts of an atom before exploring the concept of an electron cloud.

What is the description of billiard ball model?
Because Dalton thought atoms were the smallest particles of matter, he envisioned them as solid, hard spheres, so he used wooden balls to model them.

He enrolled at Owens College, Manchester, in 1870, and in 1876 entered Trinity College, Cambridge as a minor scholar. He became a Fellow of Trinity College in 1880, when he was Second Wrangler and Second Smith’s Prizeman, and he remained a member of the College for the rest of his life, becoming Lecturer in 1883 and Master in 1918. He was Cavendish Professor of Experimental Physics at Cambridge, where he succeeded Lord Rayleigh, from 1884 to 1918 and Honorary Professor of Physics, Cambridge and Royal Institution, London

According to this model, the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge. The electrons are like plums in a pudding ]]> 2021-11-11 09:20:54 UTC https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883729139 Nuclear Atom kristannalumanog https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883734599  Rutherford's atomic model became known as the nuclear model. In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom. The electrons are distributed around the nucleus and occupy most of the volume of the atom. ]]> 2021-11-11 09:24:00 UTC https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883734599 Bohr Model kristannalumanog https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883750813  the Bohr model depicts an atom as a small, positively charged nucleus surrounded by electrons. These electrons travel in circular orbits around the nucleus. Similar in structure to the solar system, except electrostatic forces rather than gravity provide attraction. ]]> 2021-11-11 09:33:28 UTC https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883750813 James Chadwick ( 1932 ) - Kristanna Fey Lumanog kristannalumanog https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883756585  Chadwick is best known for his discovery of the neutron in 1932. A neutron is a particle with no electric charge that, along with positively charged protons, makes up an atom's nucleus. Bombarding elements with neutrons can succeed in penetrating and splitting nuclei, generating an enormous amount of energy. ]]> 2021-11-11 09:37:06 UTC https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883756585 Louis De Broglie and Erwin Schrodinger ( 1926-present kristannalumanog https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883781809  Based on de Broglie's idea that particles could exhibit wavelike behavior, Austrian physicist Erwin Schrödinger theorized that the behavior of electrons within atoms could be explained by treating them mathematically as matter waves. ]]> 2021-11-11 09:52:14 UTC https://padlet.com/ashleyconstantino/h8mr36g2z60uutp3/wish/1883781809
