The following are some statements about periodic properties i) Atomic size decreases from left to right in a period ii) The EA of 2nd element in VA, VIA, VIIA are greater than the first element iii) Acidic nature of oxides decreases and basic nature of oxides of elements increases down the group

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. The solubility in water of sulphates down the Be group is Be gt Mg gt Ca gt Sr gt Ba this is due to
