HAHA remember when we were younger and we would breathe in a little helium to make a funny voice
I wonder what's helium is made of and how it makes our voices sound like that
Let's try it again, because it's so funny...Wait what's happening!!!
Oh no we are shrinking!! Wait why are we entering an atom, I think its the helium atom?
Helium is a chemical element with the symbol (He) and the atomic number 2
helium is the second most common element (after hydrogen)
The atomic number is 2 and the definition of an atomic number ishe number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.
There are 2 protons , 2 electrons and 2 neutrons. The nucleus being in the middle and the only and outer most electron shell
Heliums atomic mass is 4.002602 and the definition of atomic mass is the mass of a single atom of a chemical element. It includes the masses of the 3 subatomic particles that make up an atom: protons, neutrons and electrons.
Helium is found in period 1 and group 8 or 18. A group is the columns on the periodic table going down and periods go across
The electron configuration of helium is 2 and the valence electron is 2
Well I heard helium is colourless, odourless and tasteless
Wow that was something!! I think the helium has finally worn off.
That was really weird but how amazing is it now that we know all this information about helium??!!
