# What Metric Unit Do You Use to Measure the Diameter of a Chlorine Atom?

## Answer

Measuring of atomic diameters is never that easy. Diameters of atoms are usually expressed in angstrom which is estimated to be equal to 1e-10 meters. Other scientists however uses picometers which is equal to 1e-12 meters. So if you want to measure the diameter of a chlorine atom, you can use angstrom or pico-meters.

 The diameter of atoms is usually measured in Angstroms (1e-10 meters) or pico-meters (1e-12 meters) The former measurement unit yields numbers around one thus is favored by scientists http://wiki.answers.com/Q/What_unit_is_used_to_mea...
 Nanometers. Definitely nanometers if those are your two options. The SI unit of measure for distance is the meter, so if it's a technical question it would be meters but on the scale http://answers.yahoo.com/question/index?qid=200809...
 The smallest unit for measuring distance is. the attometer. The attometer is equal to one 1,000,000,000,000,000,000th of a meter. This is the only unit small enough to provide some http://wiki.answers.com/Q/What_unit_is_used_to_mea...
 Millimeters - equal to a thousandth of a meter. http://wiki.answers.com/Q/What_metric_unit_is_used...
