Dalam hal tren vertikal sepanjang golongan, helium dapat dipandang sebagai [[gas mulia]] yang berada di puncak [[Unsur golongan 18|Golongan 18]], tetapi sesuai dengan diskusi di bawah, kimia hidrogen bersifat unik dan tidak mudah dimasukkan ke dalam golongan manapun.
==Posisi unsur-unsur periode 1 dalam tabel periodik==
Meskipun baik hidrogen dan helium berada dalam [[blok-s]], mereka berdua tidak berperilaku yang sama dengan unsur-unsur blok-s lainnya. Perilaku keduanya sangat berbeeda dibandingkan unsur-unsur blok-s lainnya hingga memunculkan semacam polemik tentang peletakan kedua unsur ini dalam tabel periodik.

[[Helium]] is almost always placed above [[neon]] (which is in the [[p-block]]) in the periodic table as a [[noble gas]], although it is occasionally placed above [[Beryllium]] due to their similar electron configuration.

==Position of period 1 elements in the periodic table==
Although both hydrogen and helium are in the [[s-block]], neither of them behaves similarly to other s-block elements. Their behaviour is so different from the other s-block elements that there is considerable disagreement over where these two elements should be placed in the periodic table.
