Which atom is largest? What is the smallest part of the atom that has almost no weight? Which two subatomic particles have the same mass? What is an atom that has a different number of neutrons than other atoms of the same element?
Neutrons are stable and decay very slowly. Also, neutron binds the proton and electron together in an atom. Most noteworthy, the free neutron decay very quickly as it is unstable. Electron Electron is the smallest particle of the atom. Furthermore, it revolves around the nucleus of the atom...
What is an Atom ? Definition of an atom: Atomsare the smallest particles of anelementthat have the chemical properties of that element. Atoms are therefore extremely small (thehydrogenatom is the smallest) and are sometimes described as the "basic building blocks of matter"....
Particle Physics: An elementary particle is a small part that makes up the matter or radiation, and its composition is a single particle. These particles are 61 particles in the Standard Model. Knowledge of these fundamental levels of matter and radiation helps understand the phenomena that matter...
