Question

All alkali metals are solid but hydrogen is a gas with diatomic molecules. Do you justify the inclusion of hydrogen in first group with alkali metals

Answer 1

HI,
Here is your answer:-

The similarity of hydrogen with alkali metals is ns1 configuration and ability to exhibit +1 oxidation state. Hydrogen, because of its small size and high electronegativity, it is a non-metal with high I.P It shares one electron with another hydrogen and forms diatomic molecules. Due to weak vander Waals forces of attraction it is a gas whereas in alkali metals, metallic bond is present hence they are solids. Hence, hydrogen can't be included in first group along with alkali metals.
