In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary particles ...

Activity to assess understanding of the filling of energy levels, electron shells, sub-shells and orbitals to derive electron configurations. Structured worksheets provide students with the ...

Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms (i.e. including atomic radii, ionization ...

This activity introduces electron configurations at A Level by using the 'electron hotel' as an analogy. Students follow a given set of rules to assign electrons (the people) to their orbitals (rooms) ...

Have you ever seen a science experiment video where bubbles come out of metal placed in water?Lithium and sodium are both ...

Two shaped laser pulses opened new electron excitation pathways and tracked rapid quantum dynamics in potassium atoms.

Now it is possible to see a movie of an electron. The movie shows how an electron rides on a light wave after just having been pulled away from an atom. This is the first time an electron has ever ...
