LEWIS DOT STRUCTURES October 30, 2013
LEWIS DOT STRUCTURES • Show valence electrons only and symbol of element • Shows how an atom is capable of bonding • MUST follow a pattern when putting valence electrons around the symbol • Each atom holds up to 8 ve- in outer shell (no matter who they are) • You place ve- in a clockwise motion one at a time • You can only fill in 2 per side BUT, you can’t fill in one side (with 2 ve-) until every side has one
CHEMICAL BONDING Where two or more elements come together to form NEW substances November 30, 2013
CHEMICAL BONDING • Where two or more elements come together to form NEW substances • The GOAL: to have a full outer set of electrons • Electrons may be shared between atoms • Electrons may be transferred from one atom to another
