What is the difference between valency and valence electron?

Answer 1

valence electrons are on the outer shell. they're the ones that will interact with other molecules as bonds are formed. electrons on inner shells don't interact with other molecules. they keep to themselves.

Answer 2

Valency refers to the number of bonds an atom can form with other atoms, determined by the number of electrons it needs to gain, lose, or share. Valence electrons, on the other hand, are the electrons in the outermost energy level of an atom that are involved in bonding with other atoms to form molecules. In summary, valency is the number of bonds an atom can form, while valence electrons are the electrons directly involved in forming those bonds.

Answer 3

Valence electrons are electrons in the outermost shell. Valency is the number of valence electrons an atom uses to form a chemical bond. They are related but not the same.

Answer 4

Electron configuration is how many electrons are in the atom where as valency is different
