The densities of Li, Na and K followed the order

The electronegativity values of Na, Al,P and K follows the order

Why are elements H, Li, Na and K placed in group 1 ?

The ease of adsorption of the hydrated alkali metal ions on ion-exchange resins follows the order: (a) K^(+) lt Na^(+) lt Rb^(+) lt Li^(+) (b) Na^(+) lt Li^(+) lt K^(+) lt Rb^(+) (c) Li^(+) lt K^(+) lt Na^(+) lt Rb^(+) (d) Rb^(+) lt K^(+) lt Na^(+) lt Li^(+)

Statement 1: The correct order of equivalent conductance at infinite dilution is LiCl gt NaCl gt KCl Statement 2: In case of alkali metal ions, the hydration tendency follows the order LI^(+) lt Na^(+) lt K^(+)

The main oxides formed on combustion of Li, Na and K in excess of air respectively are -
