WebNov 17, 2007 · Nov 16, 2007. #4. ace123. 250. 0. Well the loss of electrons makes the radius smaller. You know Na is one of the bigger elements size wise right? And the size decreases as you go across the periodic table. The protons don't attract the valence electrons as much as the core electrons b/c of shielding. WebIn chemistry, the lattice energy is the energy change upon formation of one mole of a crystalline ionic compound from its constituent ions, which are assumed to initially be in …
WebWe define the first electron affinity as the energy released when 1 mole of gaseous electrons are added to 1 mole of the element to form 1 mole of gaseous negative ions. First electron affinities are typically negative values. This is because when an electron is added to a neutral atom, energy is released in an exothermic process. WebTo decide whether BaS or CaO has the greater lattice energy, we need to consider the relative sizes of the ions because both compounds contain a +2 metal ion and a −2 chalcogenide ion. Because Ba 2+ lies below Ca …
WebIn this case, you would find the following data: 1-st ionization energy for Tc — 702 kJ·mol−1. 2-nd ionization energy for Tc — 1470 kJ·mol−1. 3-rd ionization energy for Tc — 2850 kJ·mol−1. 1-st ionization energy for Ir — 880 kJ·mol−1. 2-nd ionization energy for Ir — 1600 kJ·mol−1. 1 comment. WebFor example, the bond energy of the pure covalent H–H bond, D H–H, is 436 kJ per mole of H–H bonds broken: H 2 ( g) 2 H ( g) D H−H = Δ H ° = 436 kJ. Molecules with three or more atoms have two or more bonds. The sum of all bond energies in such a molecule is equal to the standard enthalpy change for the endothermic reaction that ...
