How do you write the noble-gas electron configuration for B?
The noble gas configuration is the same for all elements (
or in the case of Helium only (
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
Boron achieves the noble gas configuration by losing electrons. So
Boron is element number 5 in the Periodic Table.
Thus, its electron configuration is
The noble gas that comes before boron in the Periodic Table is helium.
Its electron configuration is
Hence, the noble gas electron configuration of boron is
