Increasing order of magnetic moment among the following species is:
$$\displaystyle Na^{+},Fe^{+3},Co^{+2},Cr^{+2}$$

The yellow colour solution of $$Na_2CrO_4$$ changes to orange red on passing $$CO_2$$ gas due to the formation of:

The transition metals are mostly :

Transition elements form complexes very readily because of:

Select the correct order of ions with respect to their ionic radii.

When $$CO_2$$ is passes into aqueous $$K_2CrO_4$$  solution, this changes to another colour. What is the another colour?

Which of the following compounds is not colored?

What would happen when as solution of potassium chromate is treated with an excess of dilute nitric acid?

Spin only magnetic moment of the compound $$Hg[Co{(SCN)}_{4}]$$ is :

Least paramagnetic property is shown by:
