Compounds are made up of different types of atoms bonded together from "summary" of Chemistry Simplified NCERT Class 11 by Sanjay Sharma
Compounds are formed when atoms of different elements combine through chemical bonding. These atoms come together to create a new substance with unique properties. For example, when sodium, a highly reactive metal, combines with chlorine, a poisonous gas, they form sodium chloride, a common table salt. In this compound, sodium atoms donate an electron to chlorine atoms, resulting in the formation of a stable ionic bond. The atoms in a compound are held together by various types of chemical bonds, such as ionic bonds, covalent bonds, or metallic bonds. Ionic bonds are formed when electrons are transferred from one atom to another, creating positively and negatively charged ions that attract each other. Covalent bonds, on the other hand, are formed when atoms share electrons to achieve a stable electron configuration. In metallic bonds, electrons are delocalized and free to move throughout the structure, giving metals their characteristic properties. The properties of a compound are different from those of its constituent elements. For example, sodium and chlorine are both highly reactive, but sodium chloride is a stable compound that is essential for life. This difference in properties is a result of the unique arrangement of atoms in the compound and the type of bonding that holds them together. The properties of a compound can be predicted based on the elements it contains and the type of bonding involved. In summary, compounds are made up of different types of atoms bonded together through chemical interactions. These bonds determine the structure and properties of the compound, which are distinct from those of the individual elements. Understanding how compounds are formed and the nature of their bonding is essential in the study of chemistry.
