WebAug 16, 2024 · The correct order of second ionisation potential of carbon, nitrogen, oxygen, fluorine is: O>F>N>C. Nitrogen: [He] 2s 2 2p 3 Oxygen: [He] 2s 2 2p 4 Florine: [He] 2s 2 2p 5 Carbon: [He] 2s 2 2p 2 After removing one electron: Nitrogen: [He] 2s 2 2p 2 - After removal of one more electron, it will have only one electron in its outermost p-subshell. WebMay 6, 2024 · Correct option (2) Li < B < Be < C < O < N < F < Ne. Explanation: Be’ and ‘N’ have comparatively more stable valence sub-shell than ‘B’ and ‘O’. Correct order of first ionisation enthalpy is: Li < B < Be < C < O < N < F < Ne

WebJan 15, 2024 · IE 1 stands for the first ionization energy: the energy the atom requires to expel the first electron from its orbital. Similarly, the second ionization energy, will be the energy needed to expel the second electron. Mg+(g) -> Mg2+(g) + e- I2 = 1,451 kJ/mol WebThe first chemical element is Cesium and the last one is Helium. The unity for ionization energy is eV. Please note that the elements do not show their natural relation towards each other as in the Periodic system.

WebOct 31, 2015 · This is almost correct, but the correct order is Sn < Pb, as shown in the image below. (From facebook) Why is this so? The electron configuration of Sn is [Kr] 5s24d105p2. The electron configuration of Pb is [Xe] 6s24f145d106p2. The 4f electrons in Pb are poor at shielding the outermost electrons. WebC) The size of an atom is constant.
