What is the difference between valency & co-valency? Plz tell me.

Valency indicates, I think, the number of electrons present on the outer energy shell of the atom. But co-valency indicates how many covalent bonds it can make, i.e. how many electrons it has to share. To find out this number you have to write down the Lewis electron dot symbol of the atom. The number of free electrons is the covalency.

Valency...or more properly valence is an atoms ability to combined with others due to it's number of outer shell electrons. Co-valence is a type of bond between atoms where the difference of their electronegativity is apporox 1.7 or less, in which case they share electrons. Any thoughts Vicki??

covalency - the number of electron pairs an atom can share with other atoms
valency - the number that represents the number of electrons that it will lose add or share when it reacts with other atoms. -- the ability of the substance to react :-)
