Why is helium different from every other element?

Answer 1

hydrogen and helium are the special elements because the electron in the outer most shell of the hydrogen is 1 but it is not a metal it is a non metal whereas in helium the electron in the outer most shell are 2 but it is not a metal there fore it is a noble gas.

Answer 2

Beacause they are the elements that are found in the sun!

Hydrogen is the most abundant and lightest element on earth. Hydrogen is all around you. Water is made up of Hydrogen(H2O) 2 hydrogen atoms and 1 oxygen atom. Hydrogen is also very combustible. It is one of the key elements used in fuel to make things burn. It is EXTREMELY flammable. I know this may seem weird because it is in water but it is a fact. The human body consists of 70% of water by weight, and the earth about 73% covered in water. Hydrogen is much lighter than air and was, at one time, used for special aircraft. Aircraft such as the Hindenburg. The Hindenburg was the "Titanic of the Sky". It was basically a hotel for rich people that could fly. The Hindenburg was filled with hydrogen and when they had the ropes down, coming in for the landing, unexpectedly started on fire. The reason, they found was because of hydrogen.


Helium does not burn, and has 92% of the lifting power of hydrogen.

Answer 3

Each element has a unique set of properties, so all elements are different from the others (although some elements have very similar properties; zirconium and hafnium, for example).

The one property of helium that used to set it apart from the others, was that it failed to form compounds with any other elements (even the other noble gases; Ne, Ar, Xe, Kr formed compounds), but that is no longer true - HeNe, HgHe10, and WHe2 have all now been detected in plasma discharges, although they contain quite exotic bonding and cannot be isolated.

The only notable unique feature of helium, therefore, is that a liquid phase of helium, Helium II, displays superfluid properties - it flows with zero friction, and as a result displays very unusual behaviour. There appear to be no other substances known that display superfluid properties.
