Where is the position of hydrogen in the periodic table? Why?
(N/A) In the modern periodic table,hydrogen is placed at the top of Group $1$ (alkali metals) because it has $1$ electron in its valence shell $(1s^1)$.
However,hydrogen also shows properties similar to halogens (Group $17$) as it requires only $1$ electron to complete its valence shell.
Due to this dual nature,its position is considered unique and is often placed separately at the top of the periodic table.
