Question

The quantum numbers for the differential
of boron atom are
​

Answer 1

Answer:

the atomic no for boron is 5

Answer 2

Answer:

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. For each of these m(l) values, s = + 1/2 and s = - 1/2 spin values also occur...so there are six more possibilities.
