Answer:
valency of an element means that how much electrons are needed in the outermost shell of the electron to complete its octet and valence electrons means how many electrons are actually present in the outermost shell of an atom in elementary state.
The relationship b/w valency and valence electrons is that they both are related with the electrons in the outermost shell.
