knowledge of electron newtron proton

Electrons, neutrons, and protons are the three basic subatomic particles that make up atoms, which are the building blocks of all matter in the universe. Electrons are negatively charged particles that are found outside the nucleus of an atom, in regions called electron shells or energy levels. They have a very small mass compared to protons and neutrons, with a mass of approximately 9.1 x 10^-31 kg. Electrons are responsible for chemical bonding, as they are involved in the interactions between atoms that form molecules. Neutrons are neutral particles found in the nucleus of an atom, along with protons. They have a slightly larger mass than protons, with a mass of approximately 1.67 x 10^-27 kg. Neutrons help to stabilize the nucleus of an atom and keep it from breaking apart, as they provide an attractive force that counteracts the repulsive force between positively charged protons. Protons are positively charged particles found in the nucleus of an atom, along with neutrons. They have a mass of approximately 1.67 x 10^-27 kg, which is about 1836 times greater than the mass of an electron. Protons determine the identity of an atom, as the number of protons in an atom's nucleus (known as the atomic number) determines which element the atom belongs to. Together, the number of protons, neutrons, and electrons in an atom determine its properties, including its atomic mass and chemical behavior.
