valency is the number electrons a particular atom can donate or accept with favourable change in electronic configuration and minimal energy increase (or maximum lowering of energy).
Covalency is the maximum number of bonds that it can form using its empty orbitals, mostly p, d and f-orbitals by sharing or accepting electrons.

Why is covalent bond stronger than electrovalent bond?
I want all of u to visualize the experiment i did.I took 2 glasses of water.In glass1 i put a teaspoon of salt(NaCl being electrovalent) and in glass2,i put a teaspoon of glucose(covalent compound).Now it is scientifically proven that salt readily forms ions(Na+ and Cl-) than glucose which takes a long time.This proves the fact that electrovalent(ionic) bonds are weaker than electrovalent. People have a myth that because covalent bonds melt faster,they are weak compared to electrovalent.This is absolutely wrong.Melting is just change in process of a compound not involving breaking of bonds at all. Hence it is clear that Covalent bonds are stronger than Electrovalent bonds. :)
Why electrovalent bond is also known as ionic bond?
Compounds with electrovalent bonds consist of charged particles called ions, which are held together by mutual electrostatic attraction. (The term "ionic bond" is more common, at least in the USA, than "electrovalent bond.")
What type of electronegativity difference exists between atoms in a covalent bond?
In a covalent bond, atoms with a small electronegativity difference share electrons almost equally, creating a nonpolar covalent bond. When there is a larger electronegativity difference, one atom pulls the shared electrons more strongly, resulting in a polar covalent bond.
What is another name for the electrovalent bond?
Another name for the electrovalent bond is an ionic bond.
What is the largest possible electronegativity difference for a bond to be covalent?
The largest possible electronegativity difference for a bond to be considered covalent is around 1.7. When the electronegativity difference between two atoms in a bond exceeds this value, the bond is usually considered ionic rather than covalent.
How many kinds of bond?
Three(3) ----viz.--1.Electrovalent,2.Covalent, & 3.Cordinate-covalent.
Why sodium chloride is electrovalent but carbon tetrachloride not?
Sodium chloride has an ionic bond, carbon tetrachloride has a covalent bond.

How can the type of bond be predicted?
Ionic bond: the difference between electronegativities of the atoms is over 2.Covalent polar bond: the difference between electronegativities of the atoms is under 2.Covalent non-polar bond: the difference between electronegativities of the atoms is cca. zero
What is another name for the electrovalent bond?
Another name for the electrovalent bond is an ionic bond.
How do you predict the type of bond between two atoms?
Some general rules are:- the difference between the electronegativities of two atoms is over 2: ionic bond- the difference between the electronegativities of two atoms is in the range 0 -2: covalent bond- the difference between the electronegativities of two atoms is approx. zero: polar covalent bond
A covalent bond formed between two elements that have an electronegativity difference of 1.6 would be?
a very polar bond.
What is the largest possible electronegativity difference for a bond to be covalent?
The largest possible electronegativity difference for a bond to be considered covalent is around 1.7. When the electronegativity difference between two atoms in a bond exceeds this value, the bond is usually considered ionic rather than covalent.
What type bond is ammonium acetate?
There are two types of bonding in ammonium sulphate. In ammonium ion, ntrogen and hydrogen are bonded by covalent bonds (intermolecular / Van Der Waals forces) as both of the elements are non-metals. Between ammonium and sulphate, both ions, they are joined together by ionic bonds.
Is the bond between fluorine and chlorine nonpolar covalent?
The electronegativity of oxygen is 3.44 and for fluorine it is 3.98. The difference in electronegativities is 0.54, so the bond between fluorine and oxygen is polar covalent.
