$Fe,$ $Co$ and $Ni$ have valuable catalytic properties in process involving
Organic compound
Oxidation
Hydrogenation
Compounds of hydrogen
Assertion : Transition metals are good catalysts.
Reason : $V_2O_5$ or $Pt$ is used in the preparation of $H_2SO_4$ by contact process.
In the ground state of cobalt atom $(Z = 27)$ there are ....... unpaired electrons and thus the atom is.......
${V_2}{O_5}$ is useful as catalyst in
Correct order of atomic Radii (Metallic radii)
Which of the following has '$6$' unpaired $f-$electrons ?
