Web10 jan. 2024 · 1. O is a singular oxygen atom. O 2 is a molecule made of two oxygen molecules. Our atmosphere is made of mostly O 2, which our bodies have evolved to breathe. We breathe in O 2 and cellular respiration requires it (C 6 H 12 O 6 +6O 2 →6CO 2 +6H 2 O). O is oxygen, while O 2 is dioxygen. WebAtomic Radius. Unlike a ball, an atom does not have a fixed radius. The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. As you can see from the diagrams, the same atom could be found to have a different radius depending on what was around it. solium and shareworks
