Both alkali metals and alkaline earth metals are s - block elements. They resemble each other respect but still there are certain dismilariaties in their properties due to number of eletrons in the valence shell different atomic radii, ionisation enthalpy, electronegativity etc. Which is least thermally stable ?

Both alkali metals and alkaline earth metals are s - block elements. They resemble each other respect but still there are certain dismilariaties in their properties due to number of eletrons in the valence shell different atomic radii, ionisation enthalpy, electronegativity etc. The correct sequence of increasing covalent character is

Electron gain enthalpy and electronegativity

Electron gain enthalpy and electronegativity

The properties of the elements such as atomic or ionic radii ionisation enthalpy, electron gain enthalpy and electronegativity are directly or indirectly related to their electronic configuration and are called periodic properties. A part the periodic table is given below : {:(C, N, O, F),(, P, S, Cl),(,,Se, Br), (,,,I):} The highest ionisation enthalpy is of
