Question

What is ionisation energy and separation energy? How to find them?

Answer 1

Ionization energy

• The ionization energy is a measure of the capability of an element to enter into chemical reactions requiring ion formation or donation of electrons
• It is the minimum energy that an electron in a gaseous atom or ion has to absorb to come out of the influence of the nucleus
• Ionization energy is the energy change during the transition from infinity to the ground state $I.E=E_{\infty }-E_{Groundstate.}$
• The Ionization energy can be caluclated by the equation$I.E=R{z}^2\left(\frac{1}{n^2}\right)where,R=Rydbergconstant,z=chargeofion,n=orbitnumber$

Separation energy

• ​Separation energy is the energy needed to remove one nucleon (or other specified particle or particles) from an atomic nucleus.
• The separation energy is different for each nuclide and particle to be removed.
• separation energy is the energy change during the transition from infinity to the excited state of the electron.$S.E=E_{\infty }-E_{excitedstate}$
