Out of KF, NaF, and RbCl, does NaF have the shortest ionic bonds as well as highest lattice energy, and RbCl have the lowest melting point?
Thanks
Thanks
What do you think, and why? Show your attempt to solve this problem.lorka150 said:Out of KF, NaF, and RbCl, does NaF have the shortest ionic bonds as well as highest lattice energy, and RbCl have the lowest melting point?

Bond length is determined by a number of factors, which, as Steve said, should be detailed in your text. Consider bond lengths of each ion and electronegativities. This page might aid your understanding.lorka150 said:Hi Geoff
I explained my reasoning in the message above you. I thought that the highest lattice and shortest bonds correspond, and I know that as you move up and to the right that they are at the strongest - therefore because F is the farthest and Na is higher than K, I chose NaF.
For the lowest melting point, I was under the impression it would be the opposite (descendig and towards the left).
Well, we'll do what we can until you do understand. First of all, do you have a chart of trends in your text?lorka150 said:Thanks for the link. I do not understand it, but thank you for your help.
Energy is the ability to do work or cause change. It comes in many forms, such as heat, light, sound, and kinetic energy.
There are many types of energy, including thermal, nuclear, electromagnetic, chemical, and mechanical energy. Each type has its own unique properties and applications.
Periodic trends refer to the patterns or trends that can be observed in the chemical and physical properties of elements as you move across a periodic table. These trends can help predict the behavior of elements and their compounds.
The periodic law states that the properties of elements are periodic functions of their atomic numbers. This means that elements with similar properties will appear at regular intervals in the periodic table.
Energy plays a crucial role in determining the physical and chemical properties of elements, which in turn affect their placement and behavior in the periodic table. For example, the amount of energy required to remove an electron from an atom (ionization energy) can help predict an element's reactivity. Additionally, the energy levels of electrons in an atom can affect an element's atomic size and chemical bonding behavior.
