PPT-Lewis Structures Honors Chemistry: Bonding

Gilbert Newton Lewis American chemist October 25 1875 March 23 1946 I have attempted to give you a glimpseof what there may be of soul in chemistry But it may have been in vain Perchance the chemist is already damned and the guardian the blackest But if the chemist has lost his soul he will not have lost his courage and as he descends into the inferno sees the rows of glowing furnaces and sniffs the homey fumes of brimstone he will call out . Criss. -Cross Method. 11/22/13 Chemistry. Drill. Draw electron dot structures for each element. . What charge do they typically have?. H. Ca. Ne. Zn (take a guess on the charge).

Valence electrons & Lewis structures. The ‘Octet rule’ . Mrs. Page. Essential Idea. Lewis (electron dot) structures show the electron domains in the valence shell and are used to predict molecular shape. .. Nature of Science. Scientists . use models as representatives of the real world – the development of the model of molecular shapes (VSEPR) to explain observable properties.. Covalent Bonding. A . chemical bond . is the force that holds two atoms together and makes them function as a unit. Atoms form bonds to become most stable and obtain an octet. Covalent Bonding: Electrons are shared between two or more elements. Always between 2 non-metals. Bonding Theories. Explain how atoms bond together to form molecules. Explain why some combinations are stable and others are not. Table salt . NaCl. …. Not NaCl. 2. Water is H. 2. O …. Not H. 3. Covalent bonds . result from the . sharing . of electrons. between two atoms.. A covalent bond is a . two-electron bond . in which the bonding atoms share valence electrons..
