Helium is a colorless, odorless, tasteless, non-toxic, inert monatomic gas that is the second lightest and second most abundant element in the observable universe, after hydrogen. Its atomic number is 2, and its chemical symbol is He. Helium is classified as a noble gas, which means it has a very low reactivity due to its filled electron shell.
