On a very simplistic level, why do atoms combine? They want to be like a certain group of elements on the periodic table. What are those, and what do they have in common? Logged vhpk Full Member Posts: 259 Mole Snacks: +12/-25 ...
Atoms are lonely hearts that are constantly in search of partners to bring stability to their lives—at Least that's the premise of our Atomic Dating Game, a chemistry activity that helps students visualize and understand how and why atoms combine. ...
In science, students spend a lot of time learning the facts and formulas of science (e.g., how atoms combine) and relatively less on the general process of the scientific method. This problem-solving process applies to any field of inquiry. I suspect very few teachers point out that every...
"Replacement of hydrogen atoms by lithium atoms may radically alter the stereochemistry of the parent hydrocarbon". Thus can be summarized some of the most important findings of the imaginative computational work of Schleyer and his coworkers. 1 What fundamental property of lithium is primarily ...
Why can't atoms gain or lose protons? Why don t atoms gain or lose protons?Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these io...
However, the model could not explain the line spectra of atoms with more than one electron. (1926) In Schrodinger’s quantum mechanical model, electrons do not move in circular orbits but exist inelectronic clouds. An electron cloud is a region of space inside a...
electric rocket would use a reactor to create electricity like a small power plant. Myers believes NASA should invest in all of them because they have different advantages for space travel. But joining the Defense Department in this nuclear-thermal test project was wise to combine resources, he ...
“It’s almost unheard of to find metals that don’t expand,” says Stefan Lohaus, a graduate student in the Department of Applied Physics and Materials Science at Caltech. “But in 1895, a physicist discovered by accident that if you combine iron and nickel, each of which has positive ...
Dalton wondered why the heavier and lighter gases in the atmosphere did not separate as oil and water do. He finally concluded that the constituent (61) must exist in the form of tiny particles or atoms and that these (62) be completely mixed together i
Atoms combine to form molecules, because the sharing or transferring of electrons result in a lower, and more stable energy state. That is, energy input from endothermic reactions are stored in the bonds; exothemic reactions release energy as heat and radiation; oxidation-reduciton reactions ...
