Question

Sodium was found to have a strong tendency to form $N{a}^{+}$ during ionic bond formation because:

• A. It is the most electropositive element
• B. Sodium has strong metallic bonding
• C. It has the tendency to attain the nearest noble gas electronic configuration of Neon $\left(Ne\right)$.
• D. None of the above

Answer 1

The correct option is C It has the tendency to attain the nearest noble gas electronic configuration of Neon $\left(Ne\right)$.

According to Kossel- Lewis theory every element will try to attain the noble gas electronic configuration of it's nearest noble gas element in order to achieve stability.
On losing 1 electron sodium will attain the configuration of $Ne$ and thus it has a very strong tendency to form $N{a}^{+}$.
