Radicals (often referred to as free radicals) are atoms, molecules, or ions with unpaired electrons or an open shell configuration. Free radicals may have positive, negative, or zero charge. With some exceptions, these unpaired electrons cause radicals to be highly chemically reactive.
Free radicals play an important role in combustion, atmospheric chemistry, polymerization, plasma chemistry, biochemistry, and many other chemical processes. In living organisms, superoxide and nitric oxide and their reaction products regulate many processes, such as control of vascular tone and thus blood pressure. They also play a key role in the intermediary metabolism of various biological compounds. Such radicals can even be messengers in a phenomenon dubbed reddox signaling . A radical may be trapped within a solvent cage or be otherwise bound.

What is an example of a radical in science?
In chemistry a radical is a species with an unpaired electron. By species this means an ion.
What does radical mean in chemistry?
In chemistry, the term "radical" refers to a molecular species that contains at least one unpaired electron, making it highly reactive. Radicals play a key role in many chemical reactions, particularly in processes like polymerization and combustion.
What is a phenoxy radical in chemistry?
A phenoxy radical is a type of reactive intermediate in organic chemistry that contains a phenyl ring (benzene ring) with an oxygen atom attached to it. Phenoxy radicals are commonly involved in radical reactions and can be stabilized by resonance delocalization of the unpaired electron around the phenyl ring.
What is the meaning of HO x in chemistry?
(OH)x is hydroxyl or hidroxyde (OH)- or radical .(OH) or an alcoholic group

What is the mechanism of action of a radical inhibitor in organic chemistry reactions?
A radical inhibitor works by reacting with and neutralizing free radicals, which are highly reactive species that can cause unwanted side reactions in organic chemistry reactions. By scavenging these radicals, the inhibitor helps to control the reaction and prevent undesired outcomes.
What chemistry can do to you?
I'm at the University of Glasgow and there you can study Forensic chemistry Medicinal Chemistry (which is the most popular) chemical physics and straight chemistry but within the straight chemistry there is inorganic, physical and organic and within that there is even more! magnetochemisty, crystallography, theoretical, solid state, catalysis, surface,radical chemistry, protein chemistry, radiochemistry and don't forget environmental chemistry. and there is so much more. Chemistry is one of the broadest sciences there is.
Is -OH an ion or a radical?
-OH is a functional group called hydroxyl group, commonly referred to as a radical in organic chemistry. It is not an ion because it does not carry a net positive or negative charge.
What is an alkynylation?
An alkynylation is an item's individual reaction wtih an alkyne in organic chemistry.

What is the chemical name for hc2?
Sorry, but there's no such chemical, not even C2H5 does exist. So, ... it doesn't have a name in chemistry.
