A molecule's shape depends on the atoms that make it up and the electrons that belong to the central atom. If the atoms arrange themselves around the central molecule so that they exist on a single two-dimensional plane, the molecule is planar. The molecule may otherwise form any of severa...
Take a look at water. Water is bound to two hydrogens and also has two lone pairs of electrons. Because of the two loan pairs, the molecule has a tetrahedral bent shape. In order to determine whether or not the molecule is polar, you have to look at the partial charge vectors. First...

Different strategies have been employed to determine the most likely binding configurations out of these multiple outcomes. Often, these approaches are based on additional refined simulations or statistical analysis of the large number of binding conformations. [56–58]. We employed a different approach...
Remember that the true colors of your agate will be revealed when it is polished or tumbled. A good way to determine what your agate will look like when polished is to get it wet – this can reveal color, pattern or translucence in your specimen. ...

These issues can determine the relative stability of short-lived reactive intermediates, which usually directly determine the path of the reaction. The basic reaction types are: addition reactions, elimination reactions, substitution reactions, pericyclic reactions, rearrangement reactions and redox reactions...
Using short pulses of light the researchers were able to create magnesium dimer Mg2 in a group of magnesium atoms. By adjusting the shape of the pulse the scientists were able to successfully increase the number of molecules that formed. To solve the problem of pinpointing the bond creation pro...
On the other hand, if you apply an electrical charge to it, its molecules move and it changes shape. Using electrical current from a battery, generator or other source, the LRAD applies electrical charge to lots of piezoelectric transducers. The transducers rapidly change their shape and create...
