😆😆😅😅HYDROGEN😬😬😄😄😄
☆Discover by Henry Cavendish.
☆In 1766.
☆He named it inflammable air.
☆lavoisier named it hydrogen because this gas produce water on reacting with oxygen.
☆lightest metal.
☆In comparison to halogen,hydrogen is less electronegative that is,it can accept electron only from more electropositive metals.
☆hydrogen has resemblance with alkali metals and also have halogen like properties .
In following factors..
▪electronis configuration
▪hydrogen from positive as well as negative ion.
▪it has electropositive nature and also have non metallic nature ..
▪Has reducing property . .
▪reaction with metals etc...😧😧😧😧

▪like halogen's chlorine has 13.0eV ionization potential and hydrogen has 13.54eV ionization potential .
▪As like halogen it is also a bad conductor of heat and electricity . .
▪ and it diatomic as like others halogen .
