Define the term ionization enthalpy. Discuss the factors affecting ionization enthalpy and its trends in the periodic table |
| Answer» ION enthalpy of an element can be defined as the amount of energy required to remove an electron from an isolated gaseous ATOM in its gaseous state.(i) Size of the atom: The larger the atomic size, smaller is the value of ionisation enthalpy. ... (iii) Nuclear CHARGE: As the nuclear charge INCREASES among ATOMS having same number of energy shells, the ionisation enthalpy increases because the force of attraction towards nucleus increases | |
