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 else can I help you with?
Is PO5 ionic or covalent?
Covalent- but! In the solid PBr5 is present as PBr4+ Br-. (So a mixture) In the vapour it decomposes to PBr3 and Br2.
What is a formula for a chemical compound?
Carbon dioxide is nonpolar because of its linear structure: O=C=O
Is the charge on a diatomic molecule called the oxidation number?
No. The oxidation number is the charge on the atom of an element, or if the bonding is covalent, what that charge would be if that bonding were ionic. A "molecule" with an electrical charge would be a polyatomic ion, not a molecule.
How do you convert line bond structures into molecular formula?
To convert a line bond structure into a molecular formula, count the number of carbons and other atoms (such as hydrogen, oxygen, etc.) directly connected to each carbon in the structure. Then, use this information to create the molecular formula by representing the number of each atom type in the molecule. Remember to follow the valency rules for each atom.
What is the chemical formula for dicarbon hexahydride?
The chemical formula for dicarbon hexahydride is C2H6. This compound is also known as ethane, which is a simple alkane consisting of two carbon atoms bonded together with six hydrogen atoms. Ethane is a colorless, odorless gas commonly used as a fuel.
What are the rules in writing chemical formula of ammonium sulphate?

Why is magnesium diboride named using covalent naming rules?
The atoms are bonded using covalent bonds.
What is the rules for naming and formula writing?
When naming compounds, follow these general rules: for ionic compounds, the metal name is written before the nonmetal name with an -ide ending (e.g. sodium chloride); for covalent compounds, use prefixes to indicate the number of atoms of each element (e.g. carbon dioxide). For writing chemical formulas, the element symbol is used with subscripts to indicate the number of atoms of each element present in the compound. Remember to balance the charges to ensure a neutral compound.
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
Is the charge on a diatomic molecule called the oxidation number?
No. The oxidation number is the charge on the atom of an element, or if the bonding is covalent, what that charge would be if that bonding were ionic. A "molecule" with an electrical charge would be a polyatomic ion, not a molecule.
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.
What is the chemical formula for berrylliumchromate?
Beryllium is Be and chromate is CrO4 Following the formula rules, the formula is: BeCrO4

What are rules of empirical formula?
An empirical formula represents the simplest whole-number ratio of elements in a compound. To determine it, you first convert the masses of each element to moles, then divide by the smallest number of moles to find the ratio. If necessary, these ratios can be multiplied to eliminate fractions, resulting in whole numbers. The empirical formula does not indicate the actual number of atoms in a molecule, which is represented by the molecular formula.
