Protons have appreciable weight and are present in the centrally placed nucleus. They do not move around and are held in place within the nucleus. In accordance with our solar system analogy, they form the sun of the nucleus
Neutrons have appreciable weight but no charge. Their main function is to hold the protons together in the nucleus. Imagine neutrons to be the rope used in tug of war between two repelling sides.
Atoms have a lot of space in them. The nucleus is so closely packed almost occupying very less to no space. To understand this better, if an atom is the size of a cricket stadium, the nucleus is the size of the cricket ball. The remaining space is just empty.
The word “atom” has a Greek origin, meaning “indivisible” or “uncuttable”. For a long time atoms were believed to be indivisible. With further experiments, they realised that atoms can be divided further into subatomic species.
Your body is made up of billions of atoms. About 99% of which are replaced every year producing new
