2/17/2024 0 Comments The atomic theoryThe distinction between metals and nonmetals is one of the most fundamental in chemistry. Gold-colored lements that lie along the diagonal line exhibit properties intermediate between metals and nonmetals they are called semimetals. This site was very helpful for my project.\) divides the elements into metals (in blue, below and to the left of the line) and nonmetals (in bronze, above and to the right of the line). This site was all i needed for my project. This site was great! it helped me actually understand atomic theory and helped a lot on my project. This website helped me a lot in science class! It has helped me and my partner to complete our task! thanks again. Thanks for helping me to understand the atomic theory. I had to figure out what atomic theory was before i could do the project on it. Thank you so much! This was very helpful, and i also decided who to do my project on. This site is very helpful for my project but i felt very sorry to say that our indian philosopher rushi kanaad's reference is not in this page. it got down right to the point, and had exactly everything i needed. Thanks! perfect for my project! anon138864 January 2, 2011 This was short and to the point, also very understanding, thank you it was a big help and makes studying easier because of the information given. "2) All atoms of a given element have are identical to each other."Īren't isotopes the same given element but different amount of nuclei? More neutrons? Name five areas where the atomic theory is used. Were there any problems with this theory? anon244370 February 1, 2012 What about Bohr? What part did he have in it? anon312838 January 9, 2013 If they were talking about the history of atoms in science, they'd have to mention a lot of other people, since the idea of tiny particles has been around for a while in both the East and the West. In this case though, I think it's talking about a specific kind of modern atomic theory, which is attributed to a particular person. KoiwiGal February 15, - Unfortunately a lot of the time science history tends to be a bit Western-centric, probably because when it is in English it's being written by a Westerner who might not know about other theories. I guess I kind of like the idea that size differences can go on forever, getting smaller and smaller or bigger and bigger so that space is infinite in more directions than we might think. Atoms might be made up of even smaller particles, there's no reason why they can't be. I think it's interesting to speculate that we may still have not found the lower limit of size for matter. I don't really understand physics when it gets that theoretical though, it seems to get very complicated and slightly wishy-washy but I'm sure it makes sense to those who are studying it. Fa5t3r February 16, - The idea that atoms are the smallest building blocks in creation is definitely not taken for granted, and in fact, they have discovered many other particle types which are smaller than atoms (although I don't think they make up atoms, they just exist alongside them). Methuselah Foundation, the Singularity Institute for Artificial Intelligence, and the Lifeboat Foundation. Passionate about stem cell research, regenerative medicine, and life extension therapies. In addition to being an avid blogger, Michael is particularly Physics, biology, astronomy, chemistry, and futurism. Michael is a longtime AllTheScience contributor who specializes in topics relating to paleontology, Regardless, from the viewpoint of today, Dalton contributed remarkably for his time, and his name continues to be revered by its association with the theory. His insistence that atoms combine in equal amounts to create compounds held back acceptance of his theory for years. The second item of point #4 is also quite incorrect, as, for instance, water is H 2O, not HO. The fifth point is also invalidated by nuclear physics, since atoms can indeed by destroyed in nuclear chain reactions. Tokamak reactors are used to research nuclear fusion at temperatures millions of degrees Kelvin.
