CHEMISTRY
... The nature of most atoms is that they are LONELY and sometimes AGGRESSIVE! Most atoms team up with or overtake other atoms in an attempt to get the “right” number of electrons. This is how molecules are formed. Only the NOBLE GASSES can exist on their own. ATOMS will switch partners when provoked. T ...
