Question

Boron does not form B3+ ions. Give reason?

Answer 1

As the Boron atom is small in size a large amount of energy is needed to remove 3 electrons from the boron atom. So Boron does not form B3+ ion.... When one electron is removed from the p orbital a He-like fulfilled s orbital is left. This is highly stable.

Answer 2

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\purple{R}}}}$

❤⭐ :REASON:⭐❤

• ❤.. Due to $\red{\tt{Non}}$_$\purple{\tt{availability}}$ of$\orange{\tt{d}}$ orbitals,boran is unable to expand its$\green{\tt{Octet}}$.
• ❤...Therefore,the maximum cobalence of boran cannot exceed4.
