topic(s): electronegativity, relate covalent- versus ionic- bond to difference in electronegativity

questions [12 points; 2 points / question]

1. what is / describe electronegativity ?

2. describe the periodic trend in electronegativity

3. what is a chemical bond ? what are the types of chemical bonds ? related the difference in electronegativity between adjacent "atoms" and the type of chemical bond between them.

4. what is a "Lewis dot diagram" (for an atom) ? what is the ocet rule ?

5. what type of atoms are involved in an ionic bond ? describe the basis of an ionic bond (using concepts of electrostatics, which is described by Couloub's law).

6. what type of atoms are involved in a covalent bond ? describe the basis of a covalent bond (using concepts of electrostatics, which is described by Couloub's law).
