Nomenclature of Simple Binary Compounds-Names to Formulas
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 compounds.
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.
- If you miss a problem three times, pressing "Show Answer" will cause the correct answer to appear.
