![]() ![]() The molecule is a small unit of matter, which exist in free state and represents the chemical properties of the substance. quarks and gluons.Įxample: H, He, Li, O, N Definition of Molecule In addition to this, the protons and neutrons are made up of constituents, i.e. The positive charge in an atom is equivalent to the negative charge. the former carry positive charge while the latter do not carry the electric charge. These protons and neutrons have almost equal masses, but they vary in charge i.e. The nucleus consists of protons and neutrons which group together at the middle of an atom. It is composed of a positively charged nucleus and surrounded by negatively charged electrons. ![]() It is an infinitesimal particle that distinctively identifies a chemical element. The term ‘atom’ in chemistry represents the elementary unit of ordinary matter that exist in free state and contains all chemical properties. Highly reactive, subject to certain exceptions Not visible through naked eyes, but can be seen with the help of magnifying microscope. Neither visible through naked eyes, nor magnifying microscope. Two or more, identical or different atoms, bonded chemically. Molecules refers to the set of atoms held together by bond, indicating the smallest unit of a compound. The tiny particle of a chemical element, which may or may not exist independently is called an atom. They often face difficulty in understanding them correctly, as both of these two are a tiny identifiable unit. What is the difference between atoms and molecules, is the basic question that arises in the mind of every chemistry student. ![]()
