The factor not affecting ionisation enthalpy is
Size of atom
Charge in the nucleus
Type of bonding in the crystal lattice
Type of electron involved
Electron is removed from an isolated neutral gaseous atom and so type of bonding in the crystalline lattice is not associated with ionization enthalpy
Define ionisation enthalpy. Discuss the factors affecting ionisation enthalpy of the elements and its trends in the periodic table.
Which type of electrons are involved in bonding?
