Nomenclature of Simple Binary Compounds-Names to Formulas
This quiz contains both ionic and covalent compounds, so refer to "Naming Chemical Compounds Sheet" for help.
This is a
basic exercise in converting names into formulas for binary compounds. Since its
effective use requires analysis of text input there are some basic rules:
- This page does not contain any transition elements and,thus, Stock
notation is not used.
- Spelling matters very much. No effort has been made to analyze input
against possible spelling errors.
- The proper atomic symbol and capitalizations must be used.
- All compounds on this page can be viewed as simple binary compound
- If you miss a problem three times, pressing "Show Answer" will cause the
correct answer to appear.
Operation:
1. The user should refer to the periodic table for the proper
atomic symbols
2. Pressing "New Compound" causes a small window to appear
with a name, an empty cell and a "Check Answer" button.
3. Enter the formula
of the compound in the cell using the following guidelines.
- The formula must be a single word. NaCl is correct Na Cl is not.
- Parentheses must be used appropriately.
- The numeric characters must be properly entered when needed. The input
will not show these as subscripts. Calcium iodide will be CaI2, for example.
Calcium nitrate will be Ca(NO3)2.
- Do not put spaces at the end of the formula.
4. Press "Check
Answer."
5. Results and score appear in the table on the top page.
