A covalent bonding can ONLY be done between a non-metal and a non-metal. Therefore there is no positive valency, because any non-metals can´t loose electrons. The result is, in comparison with ionic bonding, that the atomic structure is shared between the elements, by the other way in ionic bonding the metals just pass the electrons to the other non-metal. So in covalent bonding they SHARE.
Eg. Water :
H-O-H

What is the chemical formula for dicarbon hexahydride?
The formula for dicarbon dehydrate is C2H2. Remember that the prefix di means two and the rules for naming covalent compounds. First element is named using its name. The second is named as an aniond with the suffix -ide. Prefixes are used to denote the number of atoms of each element, except for mono.
When two atoms combine by sharing electrons it is a ionic or covalent bond?
Yes, when electrons are shared, it is said to be a covalent bond.
Does silver make ionic or covalent bonds?
Ionic. BUT because of Fajans rules silver salts have significant covalent character which expalins the low solubility of silver chloride.
Is Dinitrogen tetrachchlode ionic or covalent?
I had this same question; because dinitrogen tetroxide has 2 Nitrogen & oxygen atoms, I wrote that it is covalent. My reasoning was that it doesn't combine negative and positive charges, both nitrogen and oxygen have negative charges.
Is magnesium sulfide a ionic or covalent compound?
It depends on the rule you use to classify it. Magnesium Sulfide is ionic, if using the metal-nonmetal rule. It is polar covalent, if using the 1.7 electronegativity difference rule. Both these rules are generalizations.
What are the rules in writing chemical formula of ammonium sulphate?
The chemical formula of ammonium sulfate is (NH4)2SO4.
Why is magnesium diboride named using covalent naming rules?
The atoms are bonded using covalent bonds.
What is importance of naming chemical formula?
A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. It contains the symbols of the atoms of the elements present in the compound as well as how many there are for each element in the form of subscripts

Difference between technical writing and composition writing?
The difference between technical writing and composition writing is that the technical writing deals with writing off on the basis of rules that must be thoroughly proofread, while composition writing deals with writing from your imagination, with no guidelines or rules.
Can fiction writers break the rules of writing?
Yes you can. Some of the best selling authors have broken certain rules of writing.

How do i know when a formula is soluble?
You can determine whether a formula is soluble by referencing solubility rules. These rules provide guidelines on how different ions combine and react with each other in solution. If a combination of ions in a formula follows the solubility rules, then the formula is soluble. If it violates the solubility rules, the formula is insoluble.
How did the formula 1 got its name especially 1?
The name Formula refers to the rules that must be followed. '1' just means that the formula 1 rules are used. It refers to the specific formulae.
