Binary Nomenclature - 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.
  6. If you miss a problem three times, pressing the "Show Answer" button will cause the correct answer to appear.
