A molecule is the group of atoms bonded together for the existence of an element or compound which can tk part in any chemical reaction. For example: O2 is the molecule of oxygen gas containing two atoms of oxygen. H2SO4 is a molecule of sulphuric acid containing two atoms of hydrogen, one of sulphur and two atoms of oxygen.
An ion gets formed when an atom gains or loses electrons to obtain stable configuration. Atoms of metals lose electrons and form cations with positive charge whereas atoms of non-metals gain electrons and form anions with negative charge. Metalloids are those which can show both metallic and non-metallic properties.
