Ionic formulas are ions that are held together by electrostatic attraction.
Explanation:
Given: What are ionic formulas?
Ionic crystals have ionic formulas. They are held together by electrostatic attraction .
There is a positive ion known as a cation attracted to a negative ion called an anion. The positive or negative ion can be polyatomic (an ion that is a group of ions that together have a positive or negative charge).
Ionic formulas are not a molecular formula, they are what is called a formula unit, a ratio of ions.
Examples:
sodium chloride:
calcium chloride:
barium oxide:
iron (III) bromide:
ammonium sulfide:
ammonium carbonite:
Ionic formulae represent ionic compounds....i.e. they represent a definite chemical entity, a salt.
Explanation:
And ionic compounds are collections of ANIONS and CATIONS such that the resultant charge of the collection, the compound or salt, is ZERO... And so we could take a metal ion, say
