Term
| Names of _______ include the elements of which they are composed. |
|
Definition
|
|
Term
| Names of _______ are altered names of elements. Give an example. |
|
Definition
Element name: Flourine, F
Ion name: Flouride, F- |
|
|
Term
| Some compounds such as transition metals are made up of the same ions but the cations have different charges. What must follow the cation name to make this distinction? Give an example. |
|
Definition
Roman numerals showing the cation's charge.
Copper(I) ion, CU+
Copper(II) ion, CU2+ |
|
|
Term
| Ionic compounds have a total charge of what? |
|
Definition
|
|
Term
| What is the cation charge of Fe2O3 if one oxide ion has a charge of 2-? |
|
Definition
| The three oxide ions would then total 6- and since the ionic compound charge must be zero, then the two Fe ions must be 6+ so each Fe ion has a 3+ charge. |
|
|
Term
Using Tables 3, 4 and 5 from pgs 158-160, write the Ionic formulas for the following:
lithium oxide
beryllium chloride
titanium(III) nitride
cobalt(III) hydroxide |

|
Term
| How are covalent compounds named? |
|
Definition
Numerical prefixes tell how many atoms of each element are in the molecule.
Whichever element is farther to the right in the periodic table is named second and ends in -ide. |
|
|
Term
List the prefixes used in naming covalent compounds. |
|
Definition
1. mono- 6. hexa-
2. di- 7. hepta-
3. tri- 8. octa-
4. tetra- 9. nona-
5. penta- 10. deca- |
|
|
Term
| A compound's simplest formula is it's _________________. |
|
Definition
|
|
Term
| Name 3 different compounds that have the same empirical formula. |
|
Definition
| Formaldehyde, acetic acid, and glucose all have the empirical formula of CH20 |
|
|
Term
| What kind of formula differentiates between compounds which have the same empirical formula? |
|
Definition
|
|
Term
| Can a compound's molecular and empirical formulas be the same? |
|
Definition
| Yes for example water is the same H2O |
|
|
Term
| Why must roman numerals be included in the names of some compounds? |
|
Definition
| Compounds with the same elements but which have different charges on their cations must show the cations' charge as roman numerals following the cation element name. |
|
|
Term
| When naming ionic compounds, which comes first, the cation or the anion? |
|
Definition
| The cation, then the anion. |
|
|
Term
| One type of formula tells relative numbers of atoms whereas the other type tells the actual numbers of atoms; what are the names of the formulas and which is which? |
|
Definition
| Empirical tells relative numbers and molecular tells actual numbers. |
|
|
Term
| What type of compounds have both empirical and molecular formulas? |
|
