Answer:
covalency is the maximum number of e an element can share with another via ionic bond , covalent bond etc to acquire stable e configuration
Explanation:
it depends on various factors like absence of d orbitals in 2 period elements , inert pair effect and also on the group and period which an element belong to
eg:
1) even though fluorine has 7 e on the valance shell , being the electronegativity first rank holder it cannot share all 7 it only exibits - 1 oxidation states , meaning can only share one electron, whereas other halogens show +1,+5,+7 oxidation states , therefore covalecy of F is 1
