Question

what is an atom?

atoms are the basic units of matter and the defining structure of elements. atoms are made up of three particles: protons, neutrons and electrons. protons and neutrons reside in the center of the atom, which is called the nucleus. electrons exist in a cloud orbiting the nucleus.

protons are positively charged particles found within atomic nuclei. protons were discovered by ernest rutherford in experiments conducted between 1911 and 1919.

neutrons are uncharged particles found within atomic nuclei. neutrons were discovered by james chadwick in 1932.
