What Are Five Chemical Properties For Helium - Helium (from Greek: ἥλιος, romanized : helios, lit. 'sun') is a chemical element; it has symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Helium is the second most abundant element in the universe Only hydrogen occurs more often than helium Helium is also the second simplest of the chemical elements Its atoms consist of two protons two neutrons and two electrons Only the hydrogen atom is simpler than a helium atom The hydrogen atom has one proton one electron and no neutrons
