Assertion: Order of lattice energy for same halides are as `LiX lt NaX lt KX`.
Reason: Size of alkaline -earth metal increases from Li to K

Assertion (A): Alkaline earth metals are harder than alkali meatals. Reason (R ): Atomic radii of alkaline earth metas are smaller thant the corresponding alkali metals in the same period.

Assertion (A): Alkaline earth metals are harder than alkali meatals. Reason (R ): Atomic radii of alkaline earth metas are smaller thant the corresponding alkali metals in the same period.

Assertion : Alkaline earth metals are harder than alkali metals Reason : Atomic radii Qf alkaline earth metals are smaller than corresponding alkali metals in the same periods of periodic table

BeO and Be(OH)_(2) are amphoteric while the oxides and hydroxides of other alkaline earth metals are basic. The solubility of hydroxides increases as we move down the group from Be to Ba but the solubility of sulphates and carbonates decreases in that order the thermal stability of carbonates and sulphates of alkaline earth metals increases from Be to Ba as we move from top to bottom in the group. Which of the following metal carbonates decompses on heating ?

The solubility of hydroxides increases as we move down the group from Be to Ba but the solubility of sulphates and carbonates decreases in that order the thermal stability of carbonates and sulphates of alkaline earth metals increases from Be to Ba as we move from top to bottom in the group. The solubility in water of sulphates down the Be group is Be gt Mg gt Ca gt Sr gt Ba this is due to
