Answer:
Elements – Elements constitute the simplest chemical substances in which all the atoms are exactly the same.
Compound Definition:
Compounds – Compounds are chemical substances made up of two or more elements that are chemically bound together in a fixed ratio.
Chemistry is the study of the structures, physical properties, and chemical properties of material substances. It is very important to understand that all gases, liquids and solids are not the same. All are different in terms of their composition. This is the reason why the classification of the matter is very important.
Answer:
A compound is a substance made up of two or more elements chemically combined in a fixed proportion by mass. A compound is formed as a result of chemical reaction, between the constituent elements. The properties of compound are different from the properties of the elements from which it is formed.
Ex. A water molecule is made up of two hydrogen atoms and one oxygen atom. A single oxygen atom contains six electrons in its outer shell, which can hold a total of eight electrons. When two hydrogen atoms are bound to an oxygen atom, the outer electron shell of oxygen is filled
Characteristics of a compound
In a compound constituents are present in definite proportion by mass
The properties of a compound are different from the properties of its constituents.
The constituents of a compound cannot be separated by simple physical processes
Formation of a compound is generally accompanied by evolution of energy in the form of heat or light.
A compound has a fixed melting point and boiling point.
A compound is always homogeneous in nature.
