Chemistry Cumulative Review Latest Update Graded A+ Electronegativity The tendency of an atom to attract electrons in a chemical bond. It is not directly measurable. Metals have low electronegativity, meaning they do not hold onto electrons tightly and often lose them in reactions. Nonmetals have high electronegativity, meaning they hold onto electrons strongly and often gain electrons from other elements. Covalent Bond The sharing of electrons between two nonmetal atoms. ...

Chapter 1 Carbon and Its Compounds CHECKPOINT PROBLEMS Practice Problem 1.1 a) S — 1s2 2s2 2p6 3s2 3p4 b) Cl — 1s2 2s2 2p6 3s2 3p5 c) Na+ — 1s2 2s2 2p6 1-2 Copyright © 2018 Nelson Education Limited Practice Problem 1.2 a) Count valence electrons. Build a basic bonding framework and account for electrons used. Add remaining electrons and check for formal charges. The molecule has a lone pair on the nitrogen. All other electrons are bonding electrons. b) Count valence electrons. Build a bas...
