electrons and atoms chapter 5 - Chapters
Physicists directly observed ultracold atoms in an 'edge state,' flowing along a boundary without resistance. The research could help physicists manipulate electrons to flow without friction in ... When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus.
Understanding the Context
This attraction pulls the atoms together. The electrons end up ... The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons ...

Glimpses of the ultrafast world of electrons are changing scientists’ vision of the inner workings of atoms and molecules. The 2023 Nobel Prize in physics goes to three physicists who illuminated this ... Atoms are electrically neutral if they have an equal number of protons and electrons. Atoms that have either a deficit or a surplus of electrons are called ions. Electrons that are farthest from the nucleus may be transferred to other nearby atoms or shared between atoms.
