CHE 102 Lecture Notes - Lecture 3: Electronegativity, Covalent Bond, Bromine
Document Summary
Electronegativity: bonded atom"s ability to attract electrons to itself. Use the table to identify the type of bond the following atoms would form. O and h: s and o, c and h, n and h, c and o. Lewis dot structures represent the number of valence electrons in an atom and can be used to predict. Lewis diagrams/structures the number of bonds an atom typically forms. Lewis dot structures place a valence electron on each side of the element symbol, only pairing up when necessary. The number of unpaired electrons represents the number of bonds the atom typically forms. If the element has less or more bonds than the predicted amount, it will have a charge in the lewis structure, referred to as its formal charge. Lewis structures can be drawn for molecules to illustrate how atoms are covalently bonded.
