Hydrogen ( H ) is the chemical element with atomic number 1.
2.
Of the 94 naturally occurring elements, those with atomic numbers 1 through 82 each have at least one synthesized.
3.
"' Hydrogen "'is a chemical element in the periodic table that has the symbol H and atomic number 1.
4.
Hydrogen, with atomic number 1, has a single proton in its nucleus; Uranium ( atomic number 92 ) has ninety-two.
5.
Elements with atomic numbers 1 through 40 are all stable, while those with atomic numbers 41 through 82 ( except technetium and promethium ) are metastable.
6.
What s more, because the atomic number increases in whole numbers from one element to the next there can be no extra elements between Hydrogen ( atomic number 1 ) and Uranium ( atomic number 92 ) there can only be 92 elements, there is no room for any more.
7.
All elements from atomic numbers 1 ( hydrogen ) to 118 ( oganesson ) have been discovered or synthesized, with the most recent additions ( nihonium, moscovium, tennessine, and oganesson ) being confirmed by the IUPAC on December 30, 2015 : they complete the first seven rows of the periodic table.
8.
Of the elements with atomic numbers 1 to 92, most can be found in nature, having stable ( such as hydrogen ), or very long half-life ( such as uranium ) isotopes, or are created as common products of the decay of uranium and thorium ( such as radon ).
