Explain why hydrogen is not placed with ...

Explain why hydrogen is not placed with the halogen in the periodic table.

Text Solution

Verified by Experts

(i) Hydrogen resembles alkali metals as well as halogens,
(ii) Hydrogen resembles more alkali metals than halogens.
(iii) Electron affinity of hydrogen is much less than that of halogen atom. Hence the tendency to form hydride ion is low compared to that of halogens.
(iv) In most of its compounds hydrogen exists in +1 oxidation state. Therefore it is reasonable to place the hydrogen in group 1 along with alkali metals as shown in the latest period table published by IUPAC.
