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. 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.
