Combination of ionic charge and ionic radius give the largest lattice enthalpy for an ionic compound are:
Ionic charge = high, Ionic Radius = small
Understanding Ionic bonds
Understanding Ionic bonds Ionic bonds occur due to the handover of electrons to form positive ions and negative ions whose electron configuration is the same as that of the noble gases. Positive ions and negative ions are bound by an electrostatic force. The resulting compounds are called ionic compounds. One example that we often encounter everyday is table salt.
Well, the chemical formula for table salt is NaCl (Sodium chloride). In solid NaCl there is a bond between Na⁺ ions and Cl⁻ ions by electrostatic forces, so it is called an ionic bond. The crystal form of NaCl is a series of Na⁺ ions and Cl⁻ ions. One Na⁺ ion is surrounded by six Cl⁻ ions and one Cl⁻ ion is surrounded by six Na⁺ ions .
Formation of Ionic bond
Each element must try to have an electron configuration like that of a noble gas, either by releasing electrons or accepting electrons, so that it is stable. This electron handover event occurs in the NaCl compound/ table salt.
Na belongs to group IA where IA has 1 valence electron, so that to be stable IA must release 1 electron. If you look at the electron configuration, 11Na: 2, 8, 1. So when removing 1 electron, the last electron becomes 8 (according to the octet rule). Due to removing 1 electron, the originally neutral Na becomes charged +1 (Na⁺).
The reaction:
Na → Na⁺ + e⁻ (meaning Na loses 1 electron, see the electron is to the left of the arrow)
