How are ionization potentials of alkaline earth metals varying from Be to Ba? Why do the `2^("nd")` group elements have higher IE values than `1^("st")` group elements ?

How are IE's changing in the 1st group elements and why?

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

Which of the following is strongest base ?

Why are the elements of group 1 called alkali metals ?

The correct order of ionization potential [IP_(1)] among the IIA group elements if

The correct order of ionization potential [IP_1] among the IIIA group elements is:

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

The following are some statments about oxides of alkali metals i) The basis nature and solubility of these oxides increases from Li to Cs ii) The stability of superoxide of IA group elements increases down the group due to increase in lattice energy iii) KO_2 is organe red coloured and paramagnetic
