Question

Define ionisation enthalpy why second ionisation enthalpy deltaiH2 is larger than firstl ionisation enthalpy deltaiH1

Answer 1

Answer:

ionisation enthalpy is the amount of energy required for removing outer electron from valancy shell .

yes,delta H2 is greater then H1 because ,we need less energy to remove the first outermost electron then the second one as the distance of the electron in the outer most shell are further away to the nucleus then the conciquent electrons therefore there is less attractive force with outer electron so we can easily remove the outer electron
