 CRITICAL DIAMETER OF ELEMENTS

CRITICAL DIAMETER OF SOME COMMON ELEMENTS

         Critical diameter of some common Molecules

       ( in increasing size order, more will be adder as I find them )

  • This table gives 1) the name of the molecule,  2)the size,  the image, and 3) the ICSC reference number.
  • You can click on the links to VIEW:
    • Click on the chemical formula to "VIEW" the molecule 
    • Click on the ICSC number to "VIEW" the International Chemical Safety Card
  • Molecule size is expressed in Ângstroms
    • 1 Â = 1 Nanometer
    • 1,000 Â = 1 Micrometer ( Micron )
    • 1,000,000 Â = 1 Milimeter
      • 254,000 Â = 0.001" ( One thousan'th of an inch )
