1.	For alkali metals, which one of the following trends is incorrect?
Answer» Hydration ENERGY: `LigtNagtKgt Rb` lonization energy : `LigtNagtKgt Rb` DENSITY : `LiltNaltKltRb` Atomic size : `LI lt NaltKltRb` Solution :Density : `Li lt Na ltK ltRb` Potassium is lighter than sodium. The correct order of density is `Li lt Na ltK ltRb ltCs` `0.54lt0.86lt.0.97lt1.53lt1.90(in G CM^(-3))`
