...... ?‍? 3 years, 9 months ago

Amount of energy released when an electron is added to an isolated gaseous neutral atom is called electron gain enthalpy. It is denoted ∆egH . Higher the energy released in the process of taking an Higher the value of electron gain enthalpy of an atom, the more is the tendency to change into anion. Factors Affecting Electron Gain Enthalpy : (i) Effective Nuclear Charge. (ii) Atomic size (iii) Shielding Effect (iv) Half Filled and Fully Filled orbitals.

Deepak Raj 3 years, 9 months ago

In cases where (n+l) is the same for two orbitals (eg, 2p and 3s) the (n+l) rule says that the orbital with lower n has lower energy. In other words, the size of the orbital has a larger effect on orbital energy than the number of planar nodes.
