प्रश्न
Explain why hydrogen is not placed with the halogen in the periodic table.
उत्तर
- Hydrogen resembles alkali metals as well as halogens.
- Hydrogen resembles more alkali metals than halogens.
- The electron affinity of hydrogen is much less than that of halogen atoms. Hence the tendency to form hydride ions is low compared to that of halogens.
- In most of its compounds hydrogen exists in a +1 oxidation state. Therefore it is reasonable to place the hydrogen in group 1 along with alkali metals as shown in the latest periodic table published by IUPAC.
