An element is in $M^{3+}$ form. Its electronic configuration is $[Ar]3d^1$. The ion is:

Choose the correct option containing all elements with $d^{10}$ electronic configuration in their ground state from the following:

For the four consecutive transition elements $Cr, Mn, Fe,$ and $Co$,the correct order of stability of their $+2$ oxidation state is:

For $d-$block elements,the first ionization potential is of the order:

The number of electrons in the outermost shell of the $3d-$ transition elements generally remains:

What are the characteristics of the transition elements and why are they called transition elements? Which of the $d$-block elements may not be regarded as the transition elements?
