Which is a characteristic of all ions? O They are made of one type of atom.
O They have one overall charge.
O They are made of two or more types of atoms
OThey have two or more overall charges

They are made of one type of atoms.

Explanation:

Every ion that exists has at least one atom. If we didn't have atoms, we would not have ion because atoms make up ions.

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.
