formula units
In Chemthink Ionic Formulas, X represents an unknown element that you need to identify by determining the charge of the cation and anion in the ionic compound. By balancing the charges using X as the unknown element, you can deduce the correct formula for the compound.
Molecular compounds are formed by sharing of electrons between atoms, resulting in covalent bonds, while ionic compounds are formed by transferring electrons from one atom to another, resulting in ionic bonds. Molecular compounds have discrete molecules with defined molecular formulas, while ionic compounds do not have discrete molecules and are represented by empirical formulas showing the ratio of ions present in the compound.
Ionic
Formulas for ionic compounds are written by balancing the positive and negative charges of the ions to create a neutral compound. For covalent compounds, the subscripts in the formula indicate the number of atoms of each element present in the molecule.
The ionic compound CuCO is called copper(I) carbonate.

purer and with lower conductivity due to reduced ionic content
This is called ionic bond.

Two ions are associated by an electrostatic attraction.
The ionic compound CuCO is called copper(I) carbonate.
The ionic compound Ca3As2 is called calcium arsenide.
Formulas for covalent compounds are called molecular formulas. They show the types and numbers of atoms in a molecule.
The electrostatic attraction between oppositely charged ions forms an ionic bond.
