ns2The first ionisation energy for element J requires removing 1 electron from p subshell whichis further from the nucleus than s subshell and experience weaker electrostatic attraction.Hence, the first l.E of J is lower than the element preceding it in the same period.3、lncorrectPeriod 2 ele...
One of the elements has these ionisation energies and electron affinity (all in kJ \times mol^{-1}): E_{i1} = 503, E_{i2} = 965, E_{i3} = 3600, E_{EA} = 46. In what group (column) of the periodic table is this element found? Which e...

The correction coefficients for the ionisation chamber used in the study have been documented and made available. All experiments were conducted at the LEGX laboratory at the 'Centre National de l'Energie, des Sciences et des Techniques Nucléaires (CNESTEN) ' of Morocco, which is equipped with...
Materials for energy-related applications, which are crucial for a sustainable energy economy, rely on combining materials that form complex heterogenous interfaces. Simultaneously, progress in computational materials science in describing complex interfaces is critical for improving the understanding and perfor...
(VBM): The value of the highest occupied eigenvalue, when referenced againstEvacgives the ionisation potential (IP). Conduction band minimum (CBM): The value of the lowest unoccupied eigenvalue, when referenced againstEvacgives the electron affinity (EA). Band offset: The difference in VBM or ...
The energy dependent optical functions of the studied phases have been carried out by utilizing the complex relation(18)εω=ε1ω+iε2ω Here two parts are available, one is real, ε1ω and another is imaginary, ε2ω. Using the following formula [63], [64], the imaginary part [ε...
In ionic solids, the sum of the electron gain enthaply and the ionisation enthalpy may be positive but due to the high energy released in the formation of crystal lattice, the crystal structure gets stabilised. Born Haber's Cycle Determination of Lattice enthalpy It is not possible to ...
(recorded at 10 K) are observed. These signals are induced by the proximity effects with the Co layers. We note that the intensity scale of the PdM-edge is two-orders of magnitude smaller than that of the CoL-edge, due to the difference in photo-ionisation cross-section. The PdM2,3...
