It is part of the noble gasses the way the Periodic Table was made separated the noble gasses and hydrogen from the number with the rows I Might be wrong on this but I'm pretty sure that is correct :D
Hydrogen
They are located at group 18 in the periodic table.
The are both 'noble' gases, elements with the full compliment of electrons in their outer electron shells.
Group 18
hydrogen is in group 1, the rest in noble gases (group 18)
The noble gases are located on the far right column of the periodic table.
The noble gases are located in the group 18 of the periodic table of Mendeleev.
Hydrogen
oxygen, nitrogen, hydrogen, fluorine
Hydrogen is precursing Helium, Halogens are precursing the heavier noble gases. (F<<Ne, Cl<<Ar etc.)
Hydrogen, Nitrogen, Oxygen, Carbon and various noble gases
The are both 'noble' gases, elements with the full compliment of electrons in their outer electron shells.
They are located at group 18 in the periodic table.
Group 18
Hydrogen H2; nitrogen, N2; oxygen, O2; fluorine, F2; chlorine, Cl2
hydrogen is in group 1, the rest in noble gases (group 18)
The noble gases, (e.g. Helium) because they don't react because they have full molecular shells. Hydrogen was replaced from Helium in blimps because of this.
