how many moles of your excess reactant remain at the end of the reaction?1 AnswerChemistry10 months ago
-Moving electrons have wave like properties, and thus can only occupy those energy levels that can exactly accommodate the electron's wavelength?
-It is not possible to know both an electron's position and speed with complete certainty, thus we no longer think of an "orbit" for an electron, but instead talk about an "orbital"-a region of probable electron density.
-An electron can move from an allowed high energy orbital to an allowed low energy orbital if it absorbs energy that exactly equals the energy difference between those two orbitals.
-This energy can be supplied by light which has particle properties. A "particle" of light is called a photon, and one photon interacts with one electron.1 AnswerPhysics11 months ago
