2) Electron, proton, neutron are the types of subatomic particles in an atom.
3)Most of the metals are solids under "ordinary" conditions (i.e., 25ºC, 1 atmosphere of pressure, etc.), with the exception of mercury (Hg, element 80), which solidifies at -39ºC, and is a freely-flowing liquid at room temperature
