Example: potassium sulfide, K2S
This compound contain 2 potassium ions and 1 sulfide ion.
K3P, potassium phosphide
siF4
Oxygen would do so. The product formed would be sodium oxide, with chemical formula Na2O. It is an ionic compound with sodium and oxygen being in the ration 2:1 in a giant lattice structure, with strong electrostatic attraction between oppositely charged Na+ and O2- ions.
Nitrice Oxide, an ionic compound, often used in medicine and commonly known as, "laughing gas". (An Ionic compound id a compound formed between two ions of opposite charge.)
The formula would be K2Se
it depends if the formula. it is ionic if the bonds are formed between nonmetal and metals.
K3P, potassium phosphide
Na3P sodium phosphide
Ba 2+ and N 3- would form Ba3 N2
If strontium and tellurium form an ionic compound it would be SrTe.
The formula for cesium and iodine would be CsI.
If it's a molecular compound, the smallest amount would be one molecule. If it's an ionic compound, the smallest amount is a formula unit.
The new compound is called "sodium chloride", has the formula NaCl, and has ionic bonds.
Sodium and sulfur together in a compound represents a ionic bonds, because sodium is a metal and sulfur is a non-metal. The chemical formula for this compound would Na2S, and its name would be sodium sulfide.
It depends on the elements that are combining. if they are a metal and a nonmetal then it would be an ionic compound. If they are both nonmetals then it would be a molecular compound.
Well for sodium chloride, it would be NaCl
What you write for an ionic compound is called the formula unit, but the formula unit is almost always the same as the empirical formula. The answer to your question could not be the molecular formula because an ionic compound is not a molecule.
