The term chemical properties refers to the characteristics and behavior of a substance as a result of its molecular or ionic structure. These properties include physical attributes such as boiling point, melting point, density, solubility, reactivity, and others that are directly related to the composition and interactions between atoms or ions in the substance. Chemical properties help scientists understand how different compounds will behave when they interact with one another, which is essential for predicting chemical reactions and understanding the behavior of matter at a molecular level.
