Question

The valency of oxygen is 2 (Give scientific reason)​
​

Answer 1

There are eight electrons in oxygen. Therefore, oxygen has an electrical configuration of 2,6. To complete the octet and reach stability, it needs 8 electrons in its outermost shell, which it either accepts or accepts.

Valency:

• The valence or valency of an element in chemistry is a measurement of how well it can combine with other atoms to form chemical compounds or molecules.
• In chemistry, valence, sometimes called valency, is a characteristic of an element that establishes how many other atoms of the element each atom can interact with.
• The phrase, which was first used in 1868, is used to represent both the broad capability of a combination of an element and its numerical value.
• Example: Ammonia gas is created when one nitrogen atom and three hydrogen atoms combine. Therefore, nitrogen has a valency of 3.

Answer 2

In oxygen, there are eight electrons. The electrical configuration of oxygen is 2,6, as a result. It either accepts or accepts the 8 electrons that are required in its outermost shell to complete the octet and achieve stability.

• Chemistry's term for an element's ability to mix with other atoms to create chemical compounds or molecules is its valency, or valence.
• The valence, also known as valency, of an element in chemistry determines how many other atoms of the element each atom may interact with.
• The adage, which was first used in 1868, is used to convey both the numerical value of an element's value as well as the element's vast range of capabilities.
