mmetrical. 15. Electronegativity can influence the polarity of a molecule. 16. When electrons in a molecule are shifted away from one atom and towards another, the molecule has a dipole (two-pole) and is said to be nonpolar. (p36) 17. Hydrogen (electronegativity = 2.1) is considered an electron hog in LiH, LI→H. 18. When beryllium bonds with two hydrogen atoms, BeH2, a symmetrical, linear molecule is formed. H-Be-H

Chemistry A Week15 Molecular Shape 1105-Sec3 p20-38 True-False Mark A for True, and mark B for False. 1. The Master Architect of our universe had His master plan. A 2. Each molecule has exactly the same shape and design. 3. In an attempt to make a complex set of variables fit a man-made model, new facts and events always fit the old model. 4. The bonds in water are not similar to those in carbon tetrachloride. 5. The characteristic of elements un-pairing already paired electrons in order to form bonds is called hybridization. 6. The word hybrid means "a mixture of two different sources." 7. In chemistry a hybrid bond is a mixture of different types of electrons. 8. The halogen family has a low tendency to gain electrons. 9. The most common compound of a halogen is probably sodium chloride, table salt. 10. All members of the inert gas family react with other elements. 11. In a hybrid bond, the bonding electrons are at a compromise between orbitals. 12. All electrons attract each other. 13. When a molecule is lopsided (nonsymmetrical), with electrons not symmetrically distributed, the molecule is polar. 14. If all electrons are evenly distributed in a molecule, the molecule is symmetrical. 15. Electronegativity can influence the polarity of a molecule. 16. When electrons in a molecule are shifted away from one atom and towards another, the molecule has a dipole (two-pole) and is said to be nonpolar. (p36) 17.
