Valency refers to the ability of an element to combine with other elements.
Elements belonging to the same periodic table group have the same valency.
The valency of an element is determined by the amount of electrons in its outer shell.
The number of hydrogen atoms that interact with one atom of an element directly or indirectly is referred to as valency.
When one atom of nitrogen interacts with three atoms of hydrogen, ammonia gas is created.
Nitrogen has a valency of three as a result of this.
Final Answer :
The combining capacity of an element is referred to as its valency. Valence electrons are the electrons that are found in an atom’s outermost shell. Because the valence electrons of an atom have greater energy than all the interior electrons, they participate in chemical reactions.
