Transition metals are often paramagnetic owing to
Their high M.P. and B.P.
The presence of vacant orbitals
The presence of one or more unpaired electrons in the system
Their being less electropositive than the elements of groups $ I-A $ and $ II-A$
The number of unpaired electrons in $Z{n^{2 + }}$ is
Most stable compound among the following is
Permanent magnet is made from
Reactivity of transition elements decreases almost regularly from $Sc$ to $Cu$. Explain.
Which forms coloured salts
