Sentences with phrase «free oxygen atom»

UV radiation A free oxygen atom pulls the oxygen atom off the chlorine monoxide molecule to form O2.

When an electrically excited free oxygen atom encounters an oxygen molecule, they may bond to form ozone.

Not exact matches

There are basically two types of lines, those produced by collisions between the atoms or ions and the electrons in the surrounding gas, which are called collision lines, and which are very bright for elements such as oxygen, nitrogen and neon, and lines which are produced when ions capture free electrons, which are called recombination lines, and which are bright only for those gases with the highest abundances in the interstellar medium: hydrogen and helium.

This frees up oxygen atoms, which join up to form ozone molecules on the cooler night side (Icarus, DOI: 10.1016 / j.icarus.2011.08.010).

The voltage injects electrons into the oxygen atoms, allowing them to break free from titanium's hold and travel to the electrode, where they pick up carbon atoms from the graphite to form carbon dioxide.

When cerium oxide III is mixed with free radicals, it catalyzes a reaction that effectively defangs the ROS by capturing oxygen atoms and turning into cerium oxide IV.

But Catling's team proposes instead that the hydrogen escaped into space through a process called methane photolysis, in which the hydrogen - containing methane reacts with oxygen such that hydrogen atoms are freed.

The chemical feature that enables this suppression is a bond between two oxygen atoms — an unstable peroxide bridge that releases a tiny barrage in the form of free radicals (unpaired electrons) that can fracture parasite proteins the way an F5 twister tears apart barns.

The surprise to biochemists was that the enzyme, called FtmOx1, produces a highly reactive «helper» known as a free radical that assists in putting the oxygen atoms in the right place.

Free oxygen is not bound to another element, as are the oxygen atoms in other atmospheric gases like carbon dioxide and sulfur dioxide.

In particular, a charged molecule called hydronium, which has three hydrogen atoms and one oxygen ion, can transform into water (plus an independent hydrogen atom) if it captures a free - floating electron.

That's because the iron oxide would have incorporated the water's oxygen atoms into its structure, while the free hydrogen left behind would have floated out to space.

The hydroxyl radical consisting of one hydrogen and one oxygen atom, is one of the most common free radicals in the air and is therefore often referred as the detergent of the atmosphere.

Eventually the two oxygen atoms might break free from their carbon neighbor.

Free radicals are atoms or molecules (groups of atoms) of oxygen, nitrogen or another type, with one or more unpaired electrons.

Free radicals are oxygen atoms which can badly damage cell structures leading to lowered immune response and vulnerability to numerous degenerative diseases.

So, Chapman proposed that as soon as one of these oxygen atoms («free radicals») collided with an ordinary diatomic oxygen molecule, they would react together to form a single triatomic ozone molecule (Figure 18).
