What is radical short answer?

A radical is an atom or a group of atoms of the same or different elements that behaves as a single unit with a positive or negative charge.

What is meant by radical in biology?

Radicals are actually found throughout biology. They play a central role in cofactor biosynthesis used to expand the repertoire of enzyme-catalyzed reactions (6) and are essential for many metabolic transformations in primary and secondary metabolism and in cell signaling.

What is a radical and examples?

Scientific definitions for radical A root, such as √2, especially as indicated by a radical sign (√). A group of atoms that behaves as a unit in chemical reactions and is often not stable except as part of a molecule. The hydroxyl, ethyl, and phenyl radicals are examples. Radicals are unchanged by chemical reactions.

What is radical in medical?

adj. 1. Departing markedly from the usual or customary; extreme or drastic: a radical change in diet. 2. Medicine Relating to or being surgery that is extreme or drastic in an effort to eradicate all existing or potential disease: radical hysterectomy.

What is a radical in biology Brainly?

A radical (often, but unnecessarily called a free radical) is an atom or group of atoms that have one or more unpaired electrons. A prominent feature of radicals is that they have extremely high chemical reactivity, which explains not only their normal biological activities, but how they inflict damage on cells.

How are radicals formed?

Radicals are either (1) formed from spin-paired molecules or (2) from other radicals. Radicals are formed from spin-paired molecules through homolysis of weak bonds or electron transfer, also known as reduction. Radicals are formed from other radicals through substitution, addition, and elimination reactions.

What are radicals give 3 examples?

The compounds containing compound radicals give out compound radicals in their aqueous solutions. Examples of compounds containing compound radicals are as follows: Sulphuric acid (H2SO4): H2SO4 has compound radical SO2−4. Nitric acid (HNO3): HNO3 has compound radical NO−3.

What are radicals explain types?

A radical is a chemical entity with an unpaired electron in it. A radical can be electrically neutral, radical cation charged positively, or radical anion charged negatively. Example: In ultraviolet light, the chlorine molecule Cl2 undergoes homolysis to form two radicals of Cl.

What are radicals used for?

What is basic radical?

An ion originating from a base is known as a basic radical. It is a chemical species that contains a positive charge. Thus, it is also known as a cation. This ion is formed by removing the hydroxide ion from its base.

Who are radicals Class 9?

Radicals were the political group of people who wanted to change the existing institution, social system, and practices. They reflect the leftist views and ideologies. They wanted the government to be elected by the majority of the population.

Is radical and ion same?

Ions have a charge, whereas radicals are neutral. Also, ions in nature tend to be compensated by ions with opposite charges, whereas radicals are very reactive and thus short lived.

What causes free radicals in body?

Free radicals and oxidants play a dual role as both toxic and beneficial compounds, since they can be either harmful or helpful to the body. They are produced either from normal cell metabolisms in situ or from external sources (pollution, cigarette smoke, radiation, medication).

What is radical tumor?

Radical resection for soft tissue sarcomas removes your entire tumor, as well as some healthy tissue around it called the margin. This procedure is a common treatment for soft tissue sarcomas and may be the only treatment necessary, depending on your specific tumor.

What are examples of free radicals in the body?

Types of Free Radicals Singlet oxygen (when oxygen is “split” into single atoms with unpaired electrons) Hydrogen peroxide. Superoxides. Hydroxyl anions.

What do you mean by free radicals?

A free radical can be defined as any molecular species capable of independent existence that contains an unpaired electron in an atomic orbital. The presence of an unpaired electron results in certain common properties that are shared by most radicals. Many radicals are unstable and highly reactive.

What is Plumule in biology?

Definition of plumule 1 : the primary bud of a plant embryo usually situated at the apex of the hypocotyl and consisting of leaves and an epicotyl. 2 : a down feather.

Why are radicals so reactive?

The high reactivity of these radicals is due to the presence of one unpaired electron which tends to donate it or to obtain another electron to attain stability.

What are acidic radicals?

Acidic Radical An acid radical is the ionic part in an inorganic salt that comes from the acid during the neutralisation reaction. It is negatively charged and called an anion. An acid radical is mostly formed through the removal of a hydrogen ion from an acid.

What is a radical atom?

In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has unpaired valence electrons or an open electron shell, and therefore may be seen as having one or more “dangling” covalent bonds.

What are four examples of radicals?

Given example of basic radicals are as follows: Na+,Fe2+,Ag+,Al3+,Cr3+,Au3+,Co2+,Ni2+,Hg2+,Sn2+

How are radicals named?

A radical derived formally by the removal of one or two hydrogen atoms from an amine, imine, or amide characteristic group may be named by adding a suffix “-aminyl”, “-iminyl”, or “-amidyl”, to the name of the parent hydride for monovalent radicals and as a substituted nitrene for bivalent radicals.

How do you find a radical?

  1. Isolate the radical expression involving the variable.
  2. Raise both sides of the equation to the index of the radical.
  3. If there is still a radical equation, repeat steps 1 and 2; otherwise, solve the resulting equation and check the answer in the original equation.

Who made radicals?

Who Invented Radicals? Radicals were invented in 1525 by a German mathematician named Christoff Rudolff.

What are the parts of a radical?

Talk the Talk The radical expression ab has three major features, the radical symbol (it looks like a check mark), the index (the small number tucked outside the radical symbol), and the radicand, the quantity written beneath the horizontal bar of the radical symbol.
