Compare the chemistry of actinoids with that of the lanthanoids with speqlal reference to :- Atomic and ionic sizes.

Compare the chemistry of actinoids with that of the lanthanoids with special reference to :- Oxidation state.

Compare the chemistry of actinoids with that of the lanthanoids with special reference to :- electronic configuration.

Compare the chemistry of actinoids with that of the lantlanoids with special reference to: i. electronic configuration ii. oxidation state iii. atomic and ionic sizes and iv, chemical, reactivity.

The chemistry of the actinoid elements is not so smooth as that of the lanthanoids. Justify this statement by giving some examples from the oxidation state of these elements.

The correct order of atomic size is

Compare the electronic configurations and oxidation states of actinoids And lanthanolds.

Compare the properties of ionic and covalent compounds.

Compare the general characteristics of the first series of the transition metals with those of the second and third series metals. in the respective vertical columns. Give special emphasis on the following points: (i) electronic configurations (ii) oxidation states iii) Ionisation enthalpies and iv) atomic sizes.

Assertion (A) :KCl is more likely to show Schottky defect, while Lil is more likely to show Frenkel defect. Reason(R): Schottky defects is more likely in ionic solids in which cations and anions are of comparable size while Frenkel defect is more likely in which cations and anions have large differences in their ionic sizes.
