Curated OER
Electrons
Students discover that there are many facets to the electron in chemistry such as electron cloud. They view movies an animations of electrons. Students visit links pertaining to electrons.
Curated OER
Swinging Electrons
Students illustrate paramagnetic and diamagnetic differences due to the unfilled and filled valence shells. They prepare saturated solutions and place into test tubes.
