Atom and Mass Concept In the context of physics and chemistry, "atom" and "mass" are fundamental concepts that play a crucial role in understanding the structure and behaviour of matter. 1.      Atom : An atom is the basic unit of matter, and it constitutes the building blocks of all chemical elements. Atoms are incredibly small and cannot be seen by the naked eye. They are composed of even smaller subatomic particles, mainly protons, neutrons, and electrons. Protons : Positively charged particles found in the nucleus (centre) of the atom. Neutrons : Particles with no charge (neutral) are also found in the nucleus. Electrons : Negatively charged particles that orbit around the nucleus in energy levels or shells. The number of protons in the nucleus determines the element's identity, as each element has a unique number of protons. For example, an atom with one proton is hydrogen, while an atom with six protons is carbon. The total number of protons and neutrons i...
