balancing the charges on the ions to make a neutral compound
You need to know the charges on the positive and negative ions.
The last part is the anion, which will generally be a non metal. For example sodium chloride formula is NaCl, NOT ClNa
The anion.
The chemical formula KCl is for potassium chloride.
The potassium bromide is an ionic compound.
No. The chemical formula of an ionic compound is a formula unit and represents the lowest whole number ratio of ions in the compound. Ionic compounds are not made of molecules.
No. Not all binary compounds are ionic and not all ionic compounds are binary. An ionic compound is a compound formed by the exchange rather than the sharing of electrons. A binary compound is any compound of exactly 2 elements. Examples: Sodium chloride (NaCl, compound sodium and chlorine) is both binary and ionic. Potassium hydroxide (KOH, compound of potassium, hydrogen, and oxygen) is ionic but not binary. Water (H2O, compound of hydrogen and oxygen) is binary, but covalent, not ionic.
The cation is written first in the chemical formula for a binary ionic compound.
The anion.
The chemical formula KCl is for potassium chloride.
The formula for the binary ionic compound sodium nitride is Na3N.
Ba3N2
Zinc and chlorine react to form the binary ionic compound zinc chloride, which has the formula ZnCl2.
AgCI is nothing. AgCl (with a lowercase L) is silver chloride.
Formula: FeN
The potassium bromide is an ionic compound.
Er... What chemical formula?
