Hello, I noticed that you recently created a new page, Professor Albert Einstein(person). First, thank you for your contribution; Wikipedia relies solely on the efforts of volunteers such as you. Unfortunately, the page you created covers a topic on which we already have a page – Albert Einstein. Because of the duplication, your article has been tagged for speedy deletion. Please note that this is not a comment on you personally and we hope you will continue helping to improve Wikipedia. If the topic of the article you created is one that interests you, then perhaps you would like to help out at Albert Einstein – you might like to discuss new information at the article's talk page.
If you think the article you created should remain separate, you may contest the nomination by visiting the page and clicking the button labelled "Contest this speedy deletion". This will give you the opportunity to explain why you believe the page should not be deleted. However, be aware that once a page is tagged for speedy deletion, it may be removed without delay. Please do not remove the speedy deletion tag from the page yourself, but do not hesitate to add information in line with Wikipedia's policies and guidelines. If the page is deleted, and you wish to retrieve the deleted material for future reference or improvement, then please contact the deleting administrator, or if you have already done so, you can place a request here. Additionally if you would like to have someone review articles you create before they go live so they are not nominated for deletion shortly after you post them, allow me to suggest the article creation process and using our search feature to find related information we already have in the encyclopedia. Try not to be discouraged. Wikipedia looks forward to your future contributions. — JJMC89 (T·C) 02:40, 1 September 2015 (UTC)
Dalton's Atomic Model Theory[edit]
John Dalton, an English chemist, meteorologist and physicist, began a series of experiments which would culminate in him proposing the theory of atomic compositions – which thereafter would be known as Dalton’s Atomic Theory and would become one of the cornerstones of modern physics and chemistry. Dalton came up with this theory as a result of his research into gases. In the course of this research, he discovered that certain gases could only be combined in certain proportions, even if two different compounds shared the same common element or group of elements.
These experiments built upon two theories that had emerged near the end of the 18th century which dealt with chemical reactions. The first was the law of conservation of mass, formulated by Antoine Lavoisier in 1789, which states that the total mass in a chemical reaction remains constant – i.e. that the reactants have the same mass as the products.
The second was the law of definite proportions, first proven by the French chemist Joseph Louis Proust in 1799. This law states that if a compound is broken down into its constituent elements, then the masses of the constituents will always have the same proportions, regardless of the quantity or source of the original substance.
Studying these laws and building on them, Dalton developed his law of multiple proportions. This law states that if two elements can be combined to form a number of possible compounds, then the ratios of the masses of the second element, which combine with a fixed mass of the first element, will be ratios of small whole numbers.
In other words, elements combine at the atomic level in fixed ratios which naturally differ based on the compounds being combined, due to their unique atomic weights.
The findings became the basis of of Dalton’s Atomic Laws or Model, which focuses on five basic theorems. The first states that elements, in their purest state, consist of particles called atoms. Second, the atoms of a specific element are all the same, down to the very last atom. Third, atoms of different elements can be told apart by their atomic weights. Fourth, atoms of elements unite to form chemical compounds. And finally, atoms can neither be created or destroyed in chemical reaction, only the grouping ever changes.
Dalton also believed atomic theory could explain why water absorbed different gases in different proportions – for example, he found that water absorbed carbon dioxide far better than it absorbed nitrogen. Dalton hypothesized this was due to the differences in mass and complexity of the gases’ respective particles.
In fact, it was this very observation that is believed to be the first time that Dalton hinted at the supposed existence of atoms. In the paper which addressed gas absorption in water, which was first published in 1805, he wrote:
“Why does not water admit its bulk of every kind of gas alike? This question I have duly considered, and though I am not able to satisfy myself completely I am nearly persuaded that the circumstance depends on the weight and number of the ultimate particles of the several gases.”
Dalton proposed that each chemical element is composed of atoms of a single, unique type, and though they cannot be altered or destroyed by chemical means, they can combine to form more complex structures (i.e. chemical compounds). This marked the first truly scientific theory of the atom, since Dalton reached his conclusions by experimentation and examination of the results in an empirical fashion.
Dalton’s also began studying atomic weights based on the mass ratios in which they combined, with the hydrogen atom taken as the standard. However, Dalton was limited by the crudity of his laboratory instruments and the fact that he did not conceive that the atoms of certain elements exist in molecular form, such as pure oxygen (O2).
He also believed that the simplest compound between any two elements is always one atom each. This was best illustrated in how he thought that the chemical formula for water was HO, not H2O.
