Helium (from Greek: helios, meaning "sun") is a colorless, odorless, tasteless chemical element, the least reactive of the nearly inert noble gas elements.Its boiling and melting points are the lowest among the elements; except in extreme conditions, it exists only as a gas. At temperatures near absolute zero and standard pressure, Helium exists as a superfluid, a nearly frictionless phase of Helium Atomic Number: 2 Helium Atomic Weight: 4.0026 What is Helium?

The second lightest element, helium is a colorless, odorless, and tasteless gas that becomes liquid at -268.9 degrees Celsius. The boiling and freezing points of helium are lower than those of any other known substance. Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth.

The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. The chemical symbol for Helium is He. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Although there are nine known isotopes of helium ( 2 He) ( standard atomic weight: 4.002 602(2) ), only helium-3 ( 3. He. ) and helium-4 ( 4. He. ) are stable.
