Answer:
Crystalline salts such as cesium bromide form ionic bonds with electrostatic force of attraction.
Explanation:
Ionic compound : Ionic compounds are the compounds in which atoms or ions are held together by the electrostatic force of attraction.
Ionic bonds are formed by the complete transfer of electrons. The atom which looses the electron is considered as an electropositive atom and the atom which gains the electron is known as an electronegative atom.
Ionic bonds are formed between one metal and one non-metal.
Covalent compound : Covalent compounds are the compounds in which atoms are covalently bonded. Covalent bonds are formed by the equal sharing of electrons. Covalent bonds are formed between two non-metals.
In the given crystalline salt such as cesium bromide, cesium is a alkali metal and bromide is a non-metal that form ionic bonds with the electrostatic for of attraction.
Hence, the crystalline salts such as cesium bromide form ionic bonds with electrostatic force of attraction.
