Lewis Dot Diagrams/Electronic Configuration

LDD

LDD

elements symbol surrounded by dots represents v.e. (start from top and around, only 2 dots per side.)

Electron Configuration

allows us to predict probability of an electrons location.

Orbital Regions

• s,p,d,f

• electrons fill orbitals, which can be different shapes.

• S - 2 electrons

• P - 6 electrons

• D - 10 electrons

• F - 14 electrons

EC Formula

• (energy level)(block/orbital)(# of electrons deep)

• Be → 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p²

Noble Gas Configuration

• shorthand for EC

• [nearest FULL Noble gas](energy level)(block)(#of electrons deep)
