Answer:NiO < MgO < SrO < K2O < Cs2O

Explanation:

Explanation: Alkali metal oxides are most basic followed by alkaline earth metal oxides while transition metal oxides are least basic. Amongst alkali and alkaline earth metal oxides, basicity increases down the group. Thus, Cs2O is more basic than K2O and SrO is more basic than MgO.

The following are arranged in the  increasing order of basic character = MgO,SrO,K2O,AND Cs2O

Explanation:

The above given options are all metal oxides belonging to group 1 and group 2 .

That is they are : either alkali metals or alkaline earth metals .

Basic character : It refers to the nature of oxides .

As we know , every chemical substance has certain nature either acidic , basic or neutral .

Acidic substance

When acidic substance is dissolved in water in form acid

It turns blue litmus red .

Basic substance

When basic substance is dissolved in water , it forms hydroxide .

It turns red litmus blue .

Neutral substance

It remains the same

Basic character depends upon :

  • Size of combining atoms (metal and oxygen ): more is the size difference , more it is basic in nature .
  • Nature of combining atoms : It depends whether the given substance is metal or  non metal .

In given options : the increasing order depending upon their basic strength is : Cs2O,K2O,SrO,MgO
