Detailed explanation-1: -"A molecule can be defined as the smallest particle of an element or a compound that is capable of independent existence and shows all the properties of that substance”. Molecules are formed when atoms of the same or different elements combine.
Detailed explanation-2: -It cannot be broken into substances. The atom is the smallest particle of an element that can exist independently and retain the properties of that element. Similarly, the molecule is the smallest particle of a compound that exists independently and retains the properties of that compound.
Detailed explanation-3: -The smallest particle of a substance that has all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms.
Detailed explanation-4: -The smallest atom? If by “biggest” and “smallest", you mean mass (which is a measure of how much matter is there), then the smallest is the hydrogen atom with one proton and one electron.
Detailed explanation-5: -The basic building block unit of matter is an atom. Atom is the smallest particle of an element that retains the properties of the element. It is the smallest particle that takes part in the chemical reaction.
