Question

In which of the following metallic bond is strongest ?
(a) Fe
(b) Sc
(c) V
(d) Cr

Answer 1

CR IS RIGHT ANSWER.........

Answer 2

Chromium has the strongest metallic bond among all of the following mentioned in the options. (option d)

• Iron shows electronic configuration as [Ar] 3d⁶ 4s²; it has 4 unpaired electrons in the d orbital.
• Scandium (Sc) shows electronic configuration as [Ar] 3d¹ 4s²; it has 1 unpaired electron in d- orbital.
• The electronic configuration of Vanadium (V): [Ar] 3d³ 4s²; it has 3 unpaired electrons in d- orbital.
• The electronic configuration of Chromium (Cr): [Ar] 3d⁵ 4s¹; it has 5 unpaired electrons in d- orbital.
• The unpaired electrons in chromium in d orbitals are max(5), so among all the transition elements, chromium has the strongest metallic bond.
