WebNov 23, 2024 · Lattice energy increases with increase of charge on the ions because of their more attractive force between them. Thus +2 or -2 ions will release more lattice energy than the +1 or -1 ions. Here we can see that the lattice energy of MgO is much greater than the lattice energy of NaCl. Calculation of lattice energy 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 …

Similarly oxide ion (126pm) is much smaller than chloride ion (167pm). Former is doubly charged where as latter has only single charge. For both these reasons CaO has a much high lattice enthalpy (3414kJ/mol) … can dogs survive lyme disease

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. can dogs swallow pills
