Question

The element which has the strongest metallic bond among ${}_{11}{A}^{23}{,}_{12}{B}^{24}{,}_{13}{C}^{27}$ and ${}_{19}{D}^{39}$ is:

• A. A
• B. B
• C. C
• D. D

Answer 1

Answer: (C)

C

As per the given diagram A and D has only one electron in valance shell which is very easy to donate to the other atoms 'B' has two electrons in valence shell, so donating of electrons is quite difficult.

While in the case of 'C' valance shell has $3e^{-}$. Due to which ionization energy is high and it is most stable among all. Thus it forms strongest metallic bond.
