Describing Orbitalse-s exist in shells surrounding the nucleus
Lewis dot structures – show valence shell of e-s onlycan be used to show bonding

Describing Orbitals – cont’dBohr Models – show basically same info but
includes also the other levels used to figure out valence e-
further knowledge has shown that e-s actually move in a cloud, taking up more than just ringsmodel to the right is about
70 years out of date!!
