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. WebJul 23, 2024 · Arrange BaO, CaO, MgO, BeO, and SrO in greatest lattice energy (strongest bonds) to least lattice energy (weakest bonds) ... Looking at a periodic table, we can see all of the cations are elements from the Column II, which are known as the "alkaline earth metals". The elements further down on the periodic table have bigger …

WebLattice Energy Formula. a) For ionic lattice energy. The lattice energy formula of an equivalent ionic solid could be determined with the help of a revised formula of Coulomb’s law. The formula is as given below; U=-k’Q1Q2r0. Where: Q1& Q2=Charges on the ions; r0=Internuclear distance; k=Proportionality constant; U=Lattice energy 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. eagle claw channel
