Which of the following ions gives coloured solution
$C{u^ + }$
$Z{n^{ + 2 }}$
$A{g^ + }$
$F{e^{ + 2 }}$
Why the transition elements are hard and have high melting and boiling points?
Correct order of atomic Radii (Metallic radii)
Metre scales are made-up of alloy
The transition metals mostly are
The ionisation energies of transition elements are
