Atomic No. 2 . Atomic Mass is '4'.
It has 2 protons, 2 neutrons and 2 electrons in the atom.
It is the MOST inert element of all. (Does not explode on contact with air , fire or flame etc.,)
It exists in a monatomic state only.
It has the lowest Boiling Point at 6K, (-267 oC) and Lowest Melting point at 4K ( -269 oC).
It is an odourless and invisible gas.
It is very good for inflating balloons to make them float.

∙ 12y agohelium is after haydrogen it means hygrogen is lighter than helium. now the question arises that "Q.1"why we use helium instead of hydrogen coz hydrogen is lighter than helium.
Ans.1:hydrogen has 1 electron in its 1st shell and helium has it's complete shell with two electron. When we fill hydrogen in the baloon they form ionic bond... so it is used double...

What are the symbols for hydrogen and helium?
The chemical symbol for helium is "He."
What is the simble for helium?
The symbol of Helium is He. Helium's atomic number is 2.
Is helium paramagnetic?
AnswerThere are two variants of helium -- helium 3 and helium 4. Helium 4 is not magnetic but helium 3 is. Its magnetism is, however, of different nature than e.g. that of iron. The magnetism of helium 3 is used for medical lung imaging.
Is helium a metal or a nonmetal?
Helium is a nonmetal. Think about the helium balloon!
What can helium do?
Helium can change the tone of a humans voice in an helium-rich atmosphere.
What is latin word for helium?
'Helium' is from Classical Greece and means 'Of the Sun(Helios)'. The nearest Latin translation would be 'Solarus'.
What is the chemical used to detect gas leakage?
Helium is generally used; special spectrometers to detect helium leakage are designed.
What is special about the outer electron orbits of helium neon and argon?
unreactive
What are some chemical reactions of helium?
Helium is an inert gas; only some unstable compounds obtained in very special conditions are known now.
What is special about the outer electron orbits of helium?
Helium has only two valence electrons. All other noble gases have 8 valence electrons.
What are 2 atoms that will not bond chemically?
Helium will not bond with anything. Platinum will bond only with fluorine (and under special conditions). So, helium and oxygen will not bond, platinum and silicon will not bond, etc.
