The outermost shell electronic configuration of a transition element is:

Transition elements are named transition elements because their characters are

In chromyl chloride,the number of $d$-electrons present on chromium is same as in (Given atomic number of $Ti = 22, V = 23, Cr = 24, Mn = 25, Fe = 26$)

The most stable oxidation state of iron is:

Total number of $d$ electrons present in an element with atomic number $78$ is:

The atomic number of $Pd$ is $46$. The atomic numbers of the elements lying immediately above and below it in the same group are,respectively,.....................
