(i) A chemical compound is obtained by the chemical combination of two or more elements in a definite proportion by mass.
(ii) Compounds are homogeneous, i.e. their properties are the same throughout.
(iii) The chemical and physical properties of a compound are entirely different from those of the constituent elements. For example, hydrogen is a combustible gas, while oxygen is a supporter of combustion, but their compound, water is neither combustible nor a supporter of combustion.
(iv) During the formation of a compound from its elements, a certain amount of energy in the form of heat, light, electricity is either absorbed or evolved. For example, when carbon burns, it reacts with oxygen to form carbon dioxide is a chemical compound, and its formation from the elements involve the evolution of heat.

hey mates☺️☺️
here is ur answer,
Characteristics of chemical compounds
1} in a compound constituents are present in definite proportion by mass.
2} the properties of a compound are different from the properties of its constituents
3} the constituents of a compound cannot be separated by simple physical process
4} formation of a compound is generally accompanied by evolution of energy in the form of heat or light
5} a compound has a fixed melting point and boiling point
6} a compound is always homogeneous in nature
I hope it will help you☺️☺️
