Detailed explanation-1: -A molecule is the smallest particle of an element or compound that can exist independently. It is formed when two or more atoms are bonded chemically. For example, the element hydrogen cannot exists independently as a single atom therefore two hydrogen atoms bind chemically to form H2 molecule.
Detailed explanation-2: -When two or more atoms chemically bond together, they form a molecule.
Detailed explanation-3: -Molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules, such as proteins and DNA, can be made up of many thousands of atoms.
Detailed explanation-4: -Two or more atoms joined together chemically in a fixed proportion by mass are called molecules.
Detailed explanation-5: -Answer and Explanation: A compound is defined as two or more atoms of different elements bonded together.
