Introduction

On the earth Hydrogen exists as H2 molecule (dihydrogen). It constitutes to 10 % mass of universe. Hydrogen exit in many substances like carbohydrates, hydrocarbons etc. It is actually 3rd most abundant element

Characteristics of Hydrogen

Similarities with alkali metals – Its similarities with alkali metals are given below

Same number of valence electrons -1

Like alkali metals it has electropositive character

Oxidation state =+1, example is in HCl

It is strong reducing agent.

For Example: – Fe2O3    +      3H2 à      2Fe + 3H2O

                       Ferric Oxide   Hydrogen  Iron      Water

Difference with alkali metals –

Ionisation energy of Hydrogen is high as compared to alkali metals Ionisation Energy of alkali is less. 
Shows non -metallic behaviour metallic behaviour
Diatomic molecule as gas monoatomic
Hydrogen mostly form covalent bonds Ionic bonds
Class 11th Chemistry Hydrogen Notes and NCERT Solution

Similarities with Halogens –

  1. Hydrogen has only Ionisation energy less than noble gases.
  2. Ionisation energies of Hydrogen is 1312 kJmol-1 close to chlorine.
  3. Oxidation state of Hydrogen is -1 in many compounds.
  4. H2 is diatomic.
  5. Hydrogen is non-metallic and exists in gaseous state.

Differences with Halogen –

Hydrogen has fewer tendencies to accept electron.      They have more tendencies   to accept electron. 
It has no unshared electron pairs. They have unshared electron
Their oxide is neutral Their oxide is acidic
