When ionic compounds melt, do their state change or they are chemically changed? Or both? Since the electrostatic forces are overcame?

Ionic compounds are a type of chemical compound composed of positively charged ions (cations) and negatively charged ions (anions) that are held together by electrostatic forces. These compounds typically have a high melting and boiling point and are solid at room temperature.
Ionic compounds are formed through a process called ionic bonding, where electrons are transferred from one atom to another, resulting in the formation of ions. This transfer occurs between a metal and a nonmetal in order to achieve a stable electron configuration.
Some common properties of ionic compounds include high melting and boiling points, good electrical conductivity when dissolved in water, and the ability to form crystal structures. They are also often brittle and have high solubility in polar solvents.
The main difference between ionic and covalent compounds is the type of bonding. Ionic compounds have electrostatic bonds between ions, while covalent compounds have shared electron pairs between atoms. Additionally, ionic compounds tend to have higher melting and boiling points compared to covalent compounds.
Ionic compounds are named by writing the name of the cation (typically a metal) followed by the name of the anion (typically a nonmetal) with an -ide ending. Roman numerals may also be used to indicate the charge of the cation if it is a transition metal.
