| What is the difference between a polar molecule and a nonpolar molecule? |
|
Definition
| a nonpolar molecule is symetrical and doesn't have a negative or positive end, while a polar molecule has a positive and a negative end |
|
|
Term
| What is the differnce between a polar covalent bond and a nonpolar covalent bond? |
|
Definition
| the polar covalent bond has 2 poles with opposite charges caused by the pair of shared electrons being pulled closer to one atom. A nonpolar bond has an equal pull on the pair of shared electrons |
|
|
Term
| What is the relationship of bond strength and the number of bonds? |
|
Definition

|
Term
| What is the relationship of bond length and the number of bonds? |
|
Definition
| The greater the number of bonds, the shorter the bond length |

Term
| What are the steps in naming a molecular compound based on its formula? |
|
Definition
| Look at the formula, does the compound for an acidic aqueous solution? If yes it is an acid if no, name it like a normal compound. If yes is there oxygen present in the coupound. If no, you add hydro+the root of second element+ -ic, then acid. If the acid has oxygen, and the polyatomic ion encs with -ate, replace it with -ic. If it ends with -ite, replace it with -ous |
