Question

Define ionization enthalpy and it’s trends

Answer 1

the minimum amount of energy required to remove the most loosly bound electron in an atom is ionizationenthalpy....

Answer 2

Ionization Enthalpy:-

the energy required to remove an electron from the isolated gaseous state of the atom in it's ground state.

Trends:-

• size of atom is inversely proportional to ionization enthalpy.
• nuclear charge is directly proportional to the ionization enthalpy.
• screening effect is inversely proportional to the ionization enthalpy.
• penetrating effect is directly proportional to ionization enthalpy.
• ionization enthalpy is higher in atoms with stable electronic configuration ( high filled and fully filled configuration)
