What are the 2 compounds?
There are two basic types of compounds that differ in the nature of the bonds that hold their atoms or ions together. They are covalent and ionic compounds . Both types are described below.
What’s the characteristic of compound?
Characteristics of a compound
The properties of a compound are different from the properties of its constituents. 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.

What is difference between element and compound?
Elements are substances that are made from one type of atom. An element cannot be broken down into any other substance. ... Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction .
What are the properties of a compound answer?
- They have a fixed composition.
- They have definite properties.
- They cannot be separated physically.
In what ways are elements and compounds similar and different?
Compounds like CO2 are made of atoms put together to make stable molecules. Elements like O2 are made of atoms put together to make stable molecules. All Compounds are always made of atoms of different types to make molecules . Elements when they are molecules are always made of atoms of the same type.
