Question

Amongst the followings, select the element having highest ionization enthalpy (A) Sodium (B) Potassium (C) Beryllium (D) Magnesium

Tardigrade Admin · Accepted Answer

Ionisation enthalpy increases on moving from left to right in a period and decreases on moving down in a group. Thus, order of ionisation enthalpy is Be > Mg > Na > K

Q. Amongst the followings, select the element having highest ionization enthalpy
