Answer: The element B will have ONE unpaired electron in the p orbital.
Explanation:
The electronic configuration of each given element is as follows.
Atomic number of calcium (Ca) is 20.
Ca:
Atomic number of nitrogen (N) is 7.
N:
Atomic number of boron (B) is 5.
B:
Atomic number of argon (Ar) is 18.
Ar:
Atomic number of bromine (Br) is 35.
Br:
Therefore, boron is the only element that have one unpaired electron in the p-orbital.
Thus, we can conclude that element B will have ONE unpaired electron in the p orbital.
