He is a noble gas with 2 potons, 2 neutrons and 2 electrons which in this case are valence electrons (a full 1s orbital) as opposed to the remaining noble gases which have 8 valence electrons (a full s & p orbitals). They are nbole gases because they do not readily react to form compound, because their valence shell is full of electrons.
He is found in nature where an element under goes alpha decay - usually uranium.

Why are there more than one person who discovered hydrogen? sir William Ramsay, Nils A. Langley, and Per T. Cleve found it long after Pierre Janssen. Shouldn't the credit go to Pierre? '_'

  it is sometimes found in rocks, jen ;)

Hilium can be found in large amounts in natural gas

  2 protons. no neutrons

you get the number of neutrons by subtracting the atomic number from the atomic mass.and the protons are the same as the atomic number.

is helium at metalloid?
when was it discovered?
who discovered it?
what are its metallic/non metallic qualities?

  what other elements belong to the same chemical family of helium??

The other elements in the same chemical family as helium are Neon, Argon, Krypton, Xenon, Radon, Lutetium, and Lawrencium. Hope that helps!

im doing a project on helium due tomorrow! I need to know what period number helium is, how many valence electrons it has, and how many neutrons it has.
