Kinds of gaseous element :

• chlorine (7 kinds, 162 facts) (Cl, ²P_3/2 in ground state) - yellow-green, dense, sharp-smelling gas (Cl₂) which is a key industrial chemical
• fluorine (4 kinds, 133 facts) (F, ²P_3/2 in ground state) - pale yellow gas (F₂) which is the most reactive of all the elements, and is the strongest oxidizing agent
• hydrogen (3 kinds, 153 facts) (H, ²S_1/2 in ground state) - Colourless, odourless gas, insuluable in water. Lightest, most abundant element in the Universe. Its atom comprises one proton and one electron. The element occurs both in stars and as interstellar clouds, in regions where it may be neutral (H I regions) or ionized (H II regions). It was produced by the big bang. Hydrogen 1 is the most common isotope; deuterium, is rarer; and tritium, is radioactive.,
• inert gas (23 kinds, 395 facts) (group VIII element, noble gas)
• nitrogen (5 kinds, 134 facts) (N, ⁴S_3/2 in ground state) - colourless, odourless gas (N₂)
• oxygen (5 kinds, 125 facts) (O, ³P₂ in ground state) - colourless, odourless gas (O₂) which is very reactive
