The smaller ion of the two would be Mg²⁺. Both ions have the same electronic arrangement so the amount of shielding occuring for both ions is the same. The key difference between the ions that ...

A Born-Haber cycle shows how one mole of an ionic lattice is formed from its elements in their standard states and their standard conditions. You start with the elements in their standard states, and at e...

A titration reaction is used to calculate the conentration of an acid or alkali. The two solutions are combined, one of known and one of unknown concentration. When combined the hydrogen ions from the aci...

Metals are arranged in a regular lattice structure with the positive ions being held together via a sea of delocalised negative electrons.

Write out all the atoms that are in the equation, underneath. Then always balance the carbons first, leave the others for later. Then do the hydrogens and then the oxygens. This method is for simple equat...
