Why was the discovery of helium unusual?
Because helium was discovered by spectral methods in the Sun.
Does helium have any unusual properties?
It is chemically inert gas
What is a good catch phrase for helium?
Helium is normally a gas; at very low temperatures it does liquify, but it has no solid phase, no matter how cold it gets (it does, however, have a very unusual "superfluid" phase at temperatures approaching absolute zero).
The first element on the periodic table table of elements is helium?
No, the first element on the Periodic Table is Hydrogen, but because of its unusual behaviour it is usually placed by itself, not next to any other elements. The second element is Helium.
What is unusual about period 1 of the periodic table?
it has two element (hydrogen and helium) that are both gases although they are metallic and have a luster like tony baloney

What is the element name for He?

What is helium made from?

helium in a jar diff from helium atom
What element has 2 protons 1 neutron and 2 electrons?
Helium has 2 protons, 2 neutrons and 2 electrons. The symbol for helium is He and the atomic number is 2.
What is helium's favorite bonding partner?
Helium is an inert or noble gas. In any "normal" situation, it is unreactive and will not form chemical bonds. In certain situations where it is a plasma, helium could form a highly unstable compound with fluorine, iodine, phosphorus, sulfur or tungsten. These extremely tenuous compounds are called excimers, and they are generally only seen in the laboratory. Use the link below for more information.
Name the noble gas withe the smallest atomic number?
He- Helium. He- Helium.
