Why helium is said to be the heaviest element?
and if helium is not the heaviest one, which is?
Answer:
According to the Big Bang Theory, the matter formed was mostly hydrogen (atomic number one) with a "smattering" of the "heavier" elements helium (no. 2) and lithium (no. 3)
Since then stars have "cooked" others, the heaviest being iron (no. 26).
Then it takes a supernova to create the rest of the "natural" ones, the heaviest being uranium (no. 92).
Last I knew the periodic table had 109 listed (meitnerium being the last one officially named).
it's not the heaviest. It's almost the lightest. Hydrogen is the only element that's lighter.
I don;t know which is the heaviest... the heavy elements are unstable and created in a laboratory and only last for a millionth of a second.
Helium is the second most abundant and second lightest element in the universe .
hydrogen is the lightest element...
Helium is the second lightest, after hydrogen. The heaviest naturally occurring element is uranium. Lawrencium is the heaviest element, but is man made.

Who in the world said that? It isn't, of course...the heaviest element right now is man-made with an incredibly short half-life...Uuu-something or other!
well helium is one of the coldest, if not the coldest liquid. Just a few degrees kelvin, also a little factoid. Scientists predict that earth will run out of helium in the next couple decades or so. Due to the fact that most of the helium on earth was formed via radioactive decay.
its not the heaviest but the second lightest
