Question

The valency of an element can be determined with respect to
A)hydrogenation
B)chlorine atom
C) oxygen atom
D) All of these

Answer 1

Answer:

all of these is the correct ✅

Answer 2

Answer:

The valency of an element can be determined with respect to chlorine atom.

Explanation:

Step 1: The outermost shell of the chlorine atom has 7 electrons. It is challenging to lose 7 electrons in order to reach the stable electrical state. As an alternative, chlorine picks up one electron to reach the octet state. Its valency is thus 1.

Step 2: The valency of an element is determined by the number of present in the atom of that element.

Step 3: In chemistry, valence, sometimes called valency, is a characteristic of an element that establishes how many other atoms of the element each atom may interact with. The phrase, which was first used in 1868, is used to represent both the broad capability of combination of an element and its numerical value.
