Answer...

Configuration of Boron (B) →

$1s^2 2s^2 2p^1$

the fifth electron is in 2p orbital.

So , n = 2

l = n - 1 = 2-1 = 1

m = -l to +l = -1 to +1

Option 1 is correct .✔️✔️

Answer 2

Answer:

Explanation:

Z = 5; (Boron): The first four electrons have the same four quantum numbers as Berylium, but the fifth electron is the first one in the l = 1 subshell which can have m(l)-values -1, 0 and +1.
