How to write a formula of an ionic and covalent compound.
*Include metals with more than one charge.
*Include polyatomic ions

Explanation:

The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. This differentiates polyatomic ions from monatomic ions, which contain only one atom. Examples of monatomic ions include \text{Na}^+Na+start text, N, a, end text, start superscript, plus, end superscript, \text{Fe}^{3+}Fe3+start text, F, e, end text, start superscript, 3, plus, end superscript, \text{Cl}^-Cl−start text, C, l, end text, start superscript, minus, end superscript, the conventions for naming ionic compounds and writing their chemical formulas.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
