“Hydrogen occupies a unique position in Modern Periodic Table”. Justify the statement.
Hydrogen is placed separately in periodic table because:
a) Considering the properties, it is similar to alkali metals
b) Based on electronic configuration it is one electron short for inert gas configuration which is similar to halogens
c) Some of the properties do not resemble with alkali metals like the nature of oxides. Hydrogen oxide (H2O) is neutral but alkali
metal oxides are basic and halogen oxides are acidic.
