WHAT IS IONIZATION ENERGY

WHAT IS IONIZTION ENERGY 

The minimum energy required to remove most loosely  bonded outermost   shell electron in the ground state from an isolated  gaseous atom is known as ionization   energy,,,,,,,,

The minimum energy required to remove most loosely bonded outermost shell electron in a ground state from an isolated gaseous know as ionization energy,,,,,,,,, note) ionization energy is positive energy (endothermic),,,,,,,,,,, unit is electron bolt\ atom or kg Jule \atom 
ex,,,,,       X(g) + energy → X⁺(g) + e⁻ 

TYPES OF IONIZATION ENERGY

first ionization energy,,,,, required to remove the  first electron from a neutral atom  is called as first ionization energy  

M + ∆H1st → M+ + e– ; ∆H1st = First Ionization 

SECOND IONIZATION ENERGY,,,,, the energy required to remove to the second electron from unipositive  ion is called as second ionization energy 

M+ + ∆H2nd →M2+ + e– ; ∆H2nd = Second Ionization 

SAME AS THIRD I.E. 

ORDER OF  I.E.,,,,,,,,,,,,,,,,,,

∆H1st < ∆H2nd < ∆H3rd < 

FACTOR AFFECTION OF I.E.

1)when atomic size increases then  I.E is decreased 2)effective nuclear charge then I.E. is increses3)when screening effect is increased then I.E. has decreased 4)basic nature increases then I.E. decreases    

MOST IMPORTANT IS ELECTRONIC CONFRIGATION 

1)half-filled and full filled electronic configuration are more stable than the other ex,,,,,, N and O      N is more I.E.because of  N  electronic configuration is half-filled   2) down the g.p. I.E is decreases  
3)when the oxidation number increases then I.E. increases,,,,,,,,,,,,,,,,,,,,
