Electron Dot Structures (aka Lewis Diagrams)

Molecular Structure. Electron Dot Structures (aka Lewis Diagrams). Learning Objective. TLW express the arrangement of electrons in atoms through Lewis Valence Electron Dot Structures (TEKS 6.E.) TLW be able to construct Lewis Dot Diagrams to illustrate ionic and compounds (TEKS 7.C). Agenda.
