Simple ratio among the combining ions (emperical formula)
The formula for an ionic compound like magnesium chloride is expressed in terms of the ratio of cations to anions to achieve overall charge neutrality. In this case, the formula would be MgCl2, showing that one magnesium ion (Mg2+) combines with two chloride ions (Cl-) to form the compound.
Sodium chloride is an ionic compound; the term "molecule" is not adequate because NaCl form large lattices.
I'm not sure what you mean by "purely covalent", since the ionic-vs-covalent distinction is expressed in terms of electronegativity, which can take a range of values (higher values = more ionic). CO is very much a covalent compound though.
For an ionic compound, the name of the positive ion comes first, followed by the name of the negative ion. It also tells the ratio of the atoms and tells what atoms make up the compound.they describe the type and number of atoms in a molecule of the compound
A telephone receiver is not a compound itself, but the materials used to make it can be either ionic or covalent compounds. The components of a telephone receiver, such as plastics and metals, are typically made of covalent compounds.

The term formula mass is generally defined as the mass of a unit cell in an ionic compound. Molecular compounds are just defined in terms of molecular mass.

The formula for calculating the area of a circle in terms of the radius is A r2, where A represents the area and r is the radius of the circle, expressed in square units.
covalent compounds --------- It is inadequate to discuss about a telephone in terms of ionic and covalent compounds.
This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.
To determine the empirical formula of a compound, you need the molar masses of its elements and their ratio in the compound. Calculate the ratio of the elements in terms of whole numbers, which will give you the empirical formula.
