How do you write the noble-gas electron configuration for B?

The noble gas configuration is the same for all elements (s^2p^6)
or in the case of Helium only (s^2 )

Explanation:

B for Boron does not achieve the noble gas configuration by adding electrons so it does not reach the configuration of the noble gas Neon Ne_10 ( 2s^2 2p^6)

Boron achieves the noble gas configuration by losing electrons. So
B_5^11 losing three electrons to achieve the noble gas configuration of He_2^4 ( 1s^2)

The noble gas electron configuration boron is "[He]2s"^2 "2p".

Explanation:

Boron is element number 5 in the Periodic Table.

Thus, its electron configuration is "1s"^2 "2s"^2 "2p".

The noble gas that comes before boron in the Periodic Table is helium.

Its electron configuration is "1s"^2.

Hence, the noble gas electron configuration of boron is "[He]2s"^2 "2p".
