Bullet-proof steel alloy is prepared by using
$Sc$
$Ni$
$Zr$
$Zn$
Why transition elements form a coloured compounds?
Consider the hydrated ions of $Ti^{2+}, V^{2+}, Ti^{3+}$ and $Sc^{3+}$. The correct order of their spin-only magnetic moments is
The correct order of density is
Metre scales are made-up of alloy
Which of the following complex ion has a magnetic moment same as $[Cr(H_2O)_6]^{3+}$ ?
