Q:

What is the atomic radius of CO2 in molecular geometry?

A:

Quick Answer

The distance of each oxygen atom from the central carbon atom in a molecule of carbon dioxide CO2 is 1.1621 angstroms, according to the National Institute of Standards and Technology's Computational Chemistry Comparison and Benchmark Database. Angstroms are commonly used in measurements of extremely small lengths.

Full Answer

Point group information in the Computational Chemistry Comparison and Benchmark Database indicates that the carbon dioxide molecule is linear and centrosymmetric. The carbon to oxygen bonds are each 1.1621 angstroms in length. One angstrom is one ten-billionth of a meter, and 1.1621 angstroms is equal to 116.21 picometers. The relatively short bond length is consistent with the double bond structure of CO2.
