Question

Please help me with this question;-;​

Answer 1

Small covalent molecule

• Boron has a very little structure

Lets check the Electronic configuration

z=5

`\\ \rm\hookrightarrow 1s^22s^22p^1`

Option A is correct

Answer 2

High melting point of boron is due to its existence as

• Small covalent molecule

Boron has a melting point of 2353 Kelvin and this is because boron atoms have small covalent bonds which makes the atom compact and hence it has a high melting point...~
