When scientists think about what drives chemistry in space, high-energy radiation, such as X-rays, gamma rays, and ions, gets most of the attention. But a new study suggests that low-energy electrons ...

"Accurately describing electrons on individual fragments is possible, but then you lose the global picture of how charges move across a material," explained Daniel King, co-first author of the paper. ...

On the move: time sequence of the electron distribution of the molecule 1,3-cyclohexadiene after it is excited by a light pulse. (Courtesy: SLAC) Scientists in the US and UK are the first to observe ...

It is the valence electrons in an atom that participate in bonding, whereas the core electrons reside deep inside the atoms and therefore do not have any direct interactions with the surroundings. It ...

Preston J. MacDougall, a professor at Middle Tennessee State University, wanted to understand where electrons tended to reside and where they stayed away from in a crystal of a diiron cluster compound ...

Students calculate wavelength, frequency, or the velocity of a wave. Atomic Theory: Electrons on the Atom Bohr’s model of the atom are described. Students calculate wavelength, frequency, or the ...

A new study published in Physical Review Letters highlights the development of an approach to observe time-dependent changes in molecular structures. The method uses diffraction to encode the ...

For the first time, scientists have used ultrafast X-ray flashes to take a direct image of a single electron as it moved during a chemical reaction. In the new study, published Aug. 20 in the journal ...

Note: This video is designed to help the teacher better understand the lesson and is NOT intended to be shown to students. It includes observations and conclusions that students are meant to make on ...

A study suggests atoms can bond not only with electrons in their outer shells, but also via those in their supposedly sacrosanct inner shells Most of us learned in high school chemistry class that ...
