![]() In turn, ions possessing weaker charges decrease the lattice energies of their compounds. This means that ions with larger charge values will produce ionic compounds with greater lattice energies. The charges held by the constituent ions (represented by the variables Q 1 and Q 2)Īs we increase the ion charge variable, lattice energy increases. Because this process requires energy, it falls into the endothermic category, corresponding to a positive value. On the other hand, if we use the alternate definition, the dissolution of an ionic compound, the nature of the lattice energy value changes. Our first definition, the formation of an ionic compound, involves exothermic lattice energy, corresponding to a negative value. A process is exothermic when it releases energy. We can view lattice energies as either endothermic or exothermic processes depending on which definition we focus on. Depending on our chosen definition, the lattice energy of a given ionic compound may either be a positive or negative value. Lattice energy can be described as a certain quantity of energy is released when gaseous ions react during the formation of one mole of a solid ionic compound however, it also describes the energy that facilitates the dissociation of one mole of a solid ionic compound into its constituent gaseous ions. These interactions involve large amounts of energy, explaining the high melting and boiling points characteristic of ionic compounds. Their strong, rigid composition enables interactions between each charged ion and its oppositely charged counterparts. The key to understanding this concept lies in the crystalline structure of ionic compounds. ![]() We can further investigate this term in two different ways, depending on our perspective. Lattice energy maintains the fixed positions of cations and anions within ionic compounds. Both the generation and dissolution of such compounds involve the concept of lattice energy, a type of potential energy expressed in units of kJ/mol.

Users cannot flag themes manually.In this tutorial about lattice energy, we will cover its definition, relevant periodic table trends, factors that influence it, and how to calculate it. Themes will also be auto-flagged based on the questions that were chosen. Users can also deselect a question that has been auto-flagged by simply clicking on the highlighted flag (see screenshot from step 2 in "How to Flag a Question to Add to an Action Plan". However, there is no limit on what users can manually flag to bring to their action plan. This means Lattice will auto-flag at most 5 questions, with no more than 2 from every theme. Lattice will select the top 2 most actionable questions from each theme and from that set, the top 5 will be flagged. ![]() Questions with a score greater than 95 will never be auto-flagged because that high of a score indicates that engagement is already high so you might want to focus your efforts on some other areas instead. The auto-flagging feature focuses on the "actionability" of questions, which is assessed using both how low a question score is, and how high an impact score is. How Auto-Flagging WorksĪfter your survey has ended, Lattice will automatically flag a questions for you to focus on, so you can have a starting place for your Action Plan. This allows the manager to choose hyper specialized actions that are more centered towards their team. Please also note that when a manager is viewing their team's results, we will recalculate the impact scores for their team.
