What are atoms and ions with the same number of electrons (have the same electron configuration)?
Isoelectric species.
What is the trend of the sizes of isoelectric species?
Size decreases with increasing the atomic number of the element.
What do Lattice Energy trends base themselves on?
They base themselves on ionic charge mainly, and then on size.
