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...
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...
"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 ...
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 ...
How do the electronegativities of the elements vary from (a) left to right across a period and (b) from the top to the bottom of a group? Water is a compound because it\A. cannot be broken down into simpler substances.\B. always has two hydrogen ...
So, if it’s already hard to model atoms, imagine how hard it is to model thethings that make up atoms.And this is where quarks come in.Quarks combine to create things calledhadrons. That’s what protons and neutrons fall under. In fact, protons and neutrons are the most stable type...

This gas is made when you combine oxygen and hydrogen to produce an unlimited amount of energy. If this method were used to replace fossil fuels, then we could expect a significant reduction in greenhouse gas emissions. Have Burning Fossils Watered the Earth’s Climate?
