What Are the Quantum Numbers for All Electrons in Boron and Nitrogen Atoms?

Click For Summary

Discussion Overview

The discussion revolves around determining the quantum numbers for all electrons in boron and nitrogen atoms in their ground states. Participants explore the requirements of the homework question, including the interpretation of "a possible set of values" and the implications of providing quantum numbers for multiple electrons.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether providing a single set of quantum numbers (n=0, l=0, ml=0, ms=+1/2) for both boron and nitrogen is sufficient, given the phrasing of the question.
  • Another participant clarifies that the question asks for values for all electrons, implying that multiple sets of quantum numbers are needed based on the number of electrons in each atom.
  • A third participant proposes a detailed set of quantum numbers for each electron in boron and nitrogen, presenting the configurations as 1s²2s²2p¹ for boron and 1s²2s²2p³ for nitrogen, and lists the corresponding quantum numbers.
  • There is a mention of formatting issues with the presentation of quantum numbers, indicating challenges in conveying the information clearly.

Areas of Agreement / Disagreement

Participants generally agree that the question requires multiple sets of quantum numbers for all electrons in the atoms. However, there is some disagreement about the interpretation of what constitutes a "possible set" and how to present the information effectively.

Contextual Notes

Participants express uncertainty regarding the formatting of their answers and the clarity of the question's requirements. There is also a lack of consensus on the most concise way to present the quantum numbers.

Homework Statement


Give a possible set of values of the four quantum numbers for all the electrons in boron atom and a nitrogen atom if each is in the ground state.

I know the principles behind this. It comes from Zumdahl's Chemistry textbook (ninth edition, p. 345, number 95). The solutions manual however lists 5 examples for boron and 7 for nitrogen.

However, doesn't this question ask for only ONE possible set of values?

Shouldn't writing n=0 l=0 ml=0 ms=+1/2 for both boron and nitrogen enough to get the answer right?

I'm a second language speaker! Why do they say "all the electrons"? What are they asking for?
 
Physics news on Phys.org
It asks for "a" possible set of values - since there is more than one possible set, there is more than one possible correct answer. Therefore the solutions manual has to list them all.

However ... this is not the case for this problem.
Reading carefully you see it wants the set of values for all the electrons ... how many electrons does Boron have? How many does Nitrogen have? Therefore - how many values must be in each set?
 
Hmm. If I give a possible set of values for each electron in each atom, my answer would be :
BORON: 1s22s22p1
n 1 1 2 2 2
l 0 0 0 0 1
ml 0 0 0 0 -1
ms +1/2 -1/2 +1/2 -1/2 +1/2NITROGEN: 1s22s22p3
n 1 1 2 2 2 2 2
l 0 0 0 0 1 1 1
ml 0 0 0 0 -1 0 +1
ms +1/2 -1/2 +1/2 -1/2 +1/2 +1/2 +1/2

Would this answer be the most concise and thorough answer?
 
Sorry, it seems the forum does not accept long spaces. My tables are therefore not aligned.
