Question

explain difference between the valence electrons and covalency of a element ?

Answer 1

valency of an electron means the ability of an atom to form bond with other atom covalency means the number of electrons in outer most orbital of an atom.

Answer 2

Covalency refers to an element's ability to share electrons with other atoms of the same or different elements to achieve a stable electronic configuration while Valency refers to an atom's ability to make covalent connections with other atoms, whereas covalency refers to an element's ability to share electrons with other atoms of the same or different elements to achieve a stable electronic configuration.

About Valency:

• Valency refers to an element's ability to combine with other elements.
• The valency of elements belonging to the same periodic table group is the same.
• The valency of an element is determined by the amount of electrons in its outer shell.
• The valence or valency of an element is a measure of its ability to mix with other atoms to form chemical compounds or molecules in chemistry.
• Valency refers to the number of hydrogen atoms that interact directly or indirectly with one atom of an element.
• When one nitrogen atom interacts with three hydrogen atoms, ammonia gas is generated. Nitrogen, as a result, has a valency of 3.

About covalency:

• To achieve a stable electrical state, an element exchanges electrons with other atoms of the same or different elements.
• Covalency is the number of bonds created by an atom within a molecule.
• To count the number of shared electron pairs to compute the covalency draw the Lewis structure of the molecule.
