HYDROGEN
Resemblance and differences from alkali metals
● Hydrogen has configuration ns
1similar to alkali metals.
● It also forms a unipositive ion.
● It forms oxides, halides, sulfides of similar formula.
● But but….
● It has no metallic character normally
and has very high IE.
Resemblance and differences from halogens
● Hydrogen is also short by one electron to noble gas.
● It has high IE.
● It exists as diatomic molecule.
● It forms hydrides with metals.
● But But…..
● It is very less reactive non-metal as
compared to halogens.

HYDRIDES
● Dihydrogen, under certain reaction
conditions, combines with almost all
elements, except noble gases, to form
binary compounds, called hydrides.
Hydrides
Ionic or saline or salt like hydrides
Metallic or non- stoichiometric hydrides
Covalent or molecular hydrides
