WebAn atom is composed of three particles, namely, neutrons, protons and electrons with hydrogen as an exception without neutrons. Every atom has a nucleus that bounds one or more electrons around it. The nucleus has typically a similar number of protons and neutrons which are together known as nucleons.

WebThe number of protons and neutrons combine to give us the mass number of an atom. It is represented using the letter ‘A.’. As both protons and neutrons are present in the nucleus of an atom, they are together called nucleons. For example, an atom of carbon has 6 protons and 6 neutrons. Thus, its mass number is 12. WebAll matter is made up of atoms, which are tiny, indivisible particles. All the atoms of an element have the same size, mass, and properties but the atoms of different elements have different sizes and masses. Atoms cannot be created, destroyed, or …
