How Big Is an Atom?
Let us begin by saying that anything man (1) knows about the atom today might be changed tomorrow. Science constantly (2) are constantly learning new things about the atom as atom-smashing machines (3) are built. The word “atom” comes from Greeks who (4) thought an atom to be the (5) smallest possible particle of any substance. Yet today we (6) have found more than 20 different particles in the core of the atom! Scientists believe the atom (7) is made of electrons, protons, neutrons, positrons, neutrino, mesons and hyperons. How all these particles (8) are held together to make up the atom still (9) is still not known to us.
