Question

What do you mean by valency​

Answer 1

$\huge \fbox \pink{Answer:}$

In chemistry, the valence or valency of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules.

What is Valency short answer?

In other words, the valency of an element is the number of electrons an atom of the element uses to combine with atoms of other elements - it is the combining power of an atom of the element.

Answer 2

Answer:

The combining power of an element, especially as measured by the number of hydrogen atoms it can displace or combine with.

Explanation:

Valence electrons are those electrons which are present in the outermost orbit of the atom. From the Bohr-bury scheme, we can say that the outermost shell can contain a maximum of 8 electrons. Only a little chemical activity is observed when the outermost shell is completely filled. We can also say that it’s combining capacity becomes zero. For example, nitrogen forms a number of compounds with hydrogen such as NH3, N2H4, N3H in which nitrogen atoms have valencies of 3, 2 and 1/3 respectively. Thus, this concept of valency as a mere number was not clear. Therefore, later on valency was defined as the number of chemical bonds formed by an atom in a molecule.
