Unformatted text preview: – Covalent compounds are formed between elements with similar electronegativities • Usually two or more nonmetals Lewis Dot Formulas of Atoms Lewis dot formulas or Lewis dot representations are a convenient bookkeeping method for tracking valence electrons. – Valence electrons are those electrons that are transferred or involved in chemical bonding. • They are chemically important. Lewis Dot Formulas of Atoms Lewis Dot Formulas of Atoms Elements that are in the same periodic group have the same Lewis dot structures....
