Where should hydrogen be placed in the periodic table?

AI Thread Summary
The discussion centers on the classification of hydrogen in the periodic table, with some participants suggesting it could fit in group 1 or group 7. Hydrogen is often viewed as a unique element that doesn't neatly belong to any group, despite being nominally placed in group 1. The alkali metals in group 1 typically react with water, a behavior hydrogen does not share, leading to debates about its classification. Additionally, group 7 consists of transition metals, raising questions about the rationale for including hydrogen there. Overall, the conversation highlights the complexities and nuances of hydrogen's placement in the periodic table.

Hi all,

I was always of the belief that hydrogen did not belong to any group in the periodic table. After discussions, some say that a group 1 or 7 place might be more suitable. Any opinions would be welcomed hopefully from a physics point-of-view on this topic.Thanks in advance

Has anyone actually asked Hydrogen itself?
 
:smile:
 
What's wrong with where it's at?

and what, specifically, do you base this belief on ?
and don't base it on personal belief rather base it on known science :smile:

from Wiki
the alkali metals comprise the group 1 elements,[note 4] excluding hydrogen (H), which is nominally a group 1 element[4][12] but not normally considered to be an alkali metal[13][14] as it rarely exhibits behaviour comparable to that of the alkali metals.[15] All the alkali metals react with water, with the heavier alkali metals reacting more vigorously than the lighter ones.

So its a sort of "hanger on" in Group one already

again from wiki...
All known elements of group 7 are transition metals

why would you want to put hydrogen in there ?Dave

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
