Neon is a colorless, odorless, and tasteless monatomic gas, belonging to the Group VIIIA elements, called noble gases.

Balloons that are inflated with helium are often used for gifts or party decorations for birthdays, anniversaries, and other special occassions.  Helium is also used in neon signs. If the sign is a bright orange-red color, it is very likely that helium is being used.  In a liquid state, it helps to achieve very low temperatures in electronic devices.  Helium is also used in asthma treatments because it diffuses easily through the lungs. When used this way, it is mixed with oxygen.  Mixed with oxygen, it is used to create an artificial air supply for deep sea divers.  Though it is not actually a use, it is sometimes inhaled because it effects the vocal cords and makes the voice a higher pitch.
