Valency is the number of hydrogen atoms that can combine with [or displace] one atom of the element [or radical] to form a compound. For example, one atom of hydrogen combines with one atom of chlorine to form hydrogen chloride [HCl]; so, the valency of chlorine [chloride] is one. Similarly, the valency of the nitrate radical [NO3] in the compound nitric acid [HNO3] is 1, and the valency of the sulfate radical in the compound sulfuric acid [H2SO4] is 2.
For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell).
The valency of an element [or radical] is always a whole number. Elements [or radicals] with valency one are monovalent, those with valency two are divalent, and those with valency three are trivalent

How is a radical equation similar to a linear equation?
Technically,no. A radical equation has a radical (Square root) in it, and has two solutions because the square root can be positive or negative.
Why is the radical a2 b2 is not equal to a b?
Because a radical has two solutions, the positive and negative. This means that √(a2b2) has twice as many solutions as ab. ab is in fact a subset of √(a2b2).
Can a radical be negative?
In mathematics, a radical typically refers to the root of a number, such as the square root. The value under a radical can be negative, but if we're talking about real numbers, the square root of a negative number is not defined in the real number system; instead, it results in an imaginary number. However, if you're considering other radicals, like cube roots, the radical itself can yield a negative result if the number under the radical is negative.
How do you simplify negative 125 under a radical without a calculator?
It depends what power is associated with the radical.
Can you have a negative number in a radical?
maby.... maby not...
Is tin a positive radical or negative radical?
Tin ions are positive (cations).
Why can't you factor negative radical numbers?
You cannot factor negative radical numbers because the square of a number must always be positive. A negative number multiplied by a negative number produces a positive number. So, it is impossible to have a negative radical.
Is -OH an ion or a radical?
In the past -OH was considered a radical; now the recommended name is functional group.
How is a radical equation similar to a linear equation?
Technically,no. A radical equation has a radical (Square root) in it, and has two solutions because the square root can be positive or negative.
What is the square root of negative 25 in radical form?
2i radical 5 * * * * * No. it is ± i*radical(25) which is ± 5i. Not sure why the answer is requireed in radical form.
An ionic compound that forms when a metal atom or a positive radical replaces the hydrogen of an acid?
The resulting compound is called a salt. It is formed through the reaction between a metal atom or positive radical with an acid, where the metal or positive radical replaces the hydrogen in the acid molecule. This reaction results in the formation of an ionic compound with a positive metal or radical ion and a negative ion derived from the acid.
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.
How do you write the square root of negative numbers in imaginary form?
easy, lets take radical negative 3 for example. you can take out a "i" because i = the radical negative one. There fore the answer is i radical 3.
Why is the radical a2 b2 is not equal to a b?

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.
