The electronegativity difference between carbon and oxygen is small. So they will form only covalent compounds and not ionic compounds.
CO (carbon monoxide) and CO2 (carbon dioxide) are the two covalent compounds formed.
In addition they can form ions like bicarbonate ion (HCO3-) and carbonate ion (CO32-) where there is covalent bond (and not ionic) between carbon and oxygen.
CaO, calcium have a nox 2+ and the anion oxide have a nox 2-...
But, if you want to know the formula for the peroxide or the superoxide (I don't remember if exist calcium superoxide) ask again ^.~
Carbon and Oxygen do not form an Ionic Compound
Carbon is C and Oxygen is O2.
A diatomic molecule of the general formula AB is formed and the compound is generally an ionic compound.
There is no 'binary formula'. You can say that hydrogen iodide is a binary compound, that is one formed from just two elements. HI is its formula.
A compound is formed when two or more elements bond together.
A compound (a molecule) is formed.
The compound lithium chloride (LiCl) is formed.
Lithium and fluorine react together to form lithium fluoride which is an ionic compound.
Lithium sulfate - Li2SO4 Lithium sulphide - Li2S
Lithium sulfate - Li2SO4 Lithium sulphide - Li2S
lithium chloride LiCl
The formula for the compound between Lithium and Sulfur is Li2S because Lithium has a +1 charge while Sulfur has a -2. So for it to be stable, there needs to be two Lithium atoms attached to one Sulfer.
Lithium oxide - Li2O Three oxides of lithium are known: Li2O, Li2O2, LiO2.
Compounds are made by elements bonding together. They are represented by the chemical formula. The chemical formula shows the elements and their ratios in the compound.
Lithium ion is Li+ and a bromine ion (called a bromide ion) is Br- and the compound formed from them would be LiBr.
If they shock with enough force, they will form a stable ionic compoud .
The formula of lead sulfide is PbS.
BaBr2
