Book Free DemoA chemical compound is formed when two distinct elements are chemically combined i.e. chemical bonds form between their atoms.

Water\(H_2O\)
Ozone \(O_3\), Nitrogen dioxide \(NO_2\), and so on.
Compounds are a form of matter created by combining two or more elements in a specific mass ratio. Chemical methods may be used to decompose it into its constituent components.

- Two or more elements are chemically mixed in a compound.
- The elements in a compound are present in a fixed mass ratio.
- Physical methods cannot isolate the constituents of a compound.
- The constituents of a compound lose their identities, i.e., A compound's properties vary from those of its constituent elements.
Example:
Constituent elements in a compound:
Water (\(H_2O\)) has three atoms: Two hydrogen (H) atoms and one oxygen (O) atom.

Methane \(CH_4\) with five atoms: One carbon (C) atom and four hydrogen (H) atoms.
Glucose \(C_6H_{12}O_6\) contains elements of carbon \(6\), hydrogen \(12\) and oxygen \(6\) combined to form a glucose molecule.

Sodium chloride \(NaCl\) contains the two elements: sodium and chlorine atoms combined to form a sodium chloride molecule.
