The term 'kind of chemical bond in salts' can be summarized as an ionic bond. An ionic bond is a type of chemical bond formed between two ions with opposite charges. It is formed when one atom gives up electrons to another atom, resulting in the formation of positively and negatively charged ions. These ions are then attracted to each other, forming a strong bond. Ionic bonds are commonly found in salts, such as sodium chloride, and are responsible for the properties of these compounds.
