Which noble gas configuration is attained in the Lewis structure of COF2?

Click For Summary

Discussion Overview

The discussion revolves around the noble gas electronic configurations attained in the Lewis structure of the molecule COF2. Participants explore the configurations of carbon, oxygen, and fluorine, considering how they achieve full outer shells through electron sharing.

Discussion Character

  • Homework-related
  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant suggests that each element in COF2 achieves a noble gas configuration of neon.
  • Another participant explains that a noble gas has a full outer shell, particularly a full 'p' subshell, and questions which atom in COF2 is most likely to fill its p-subshell.
  • There is a discussion about fluorine having 7 valence electrons, leading to the idea that it is likely to fill its p shell to achieve the noble gas configuration of neon.
  • Participants express confusion about whether all atoms in COF2 would have full outer shells through electron sharing.
  • One participant posits that the electron needed for fluorine to fill its outer shell would originate from the carbon atom, noting that carbon and oxygen also need electrons to fill their p-subshells.
  • Another participant confirms that the initial suggestion about noble gas configurations looks correct and encourages drawing the Lewis structure.

Areas of Agreement / Disagreement

Participants express uncertainty about the specifics of how each atom achieves a noble gas configuration, and there is no consensus on the exact electron sharing mechanism in COF2.

Contextual Notes

Participants highlight the conservation of electrons in a neutral molecule and the need for clarification on the electron configurations of carbon and oxygen, but these points remain unresolved.

Homework Statement

For the elements in COF2, which noble gas electronic configuration is attained in the Lewis structure.



The attempt at a solution

I'm guessing that each element has a noble gas configuration of neon. Would that be correct. Any clarification would be greatly appreciated.

Thanks in advance.

A noble gas has a full outer shell, or more particularly, a full 'p' subshell.

For example, the electronic configuration of Kr in the ground state electron configuration is: [Ar].3d10.4s2.4p6

Similarly for Xe: [Kr].4d10.5s2.5p6

In the molecule, COF2, which element (atom) is most likely to fill its p-subshell?

Thanks for replying.

F has 7 valence electrons so I'm guessing that it's the most likely to fill its p shell which would give it the noble gas electronic configuration of neon. But when it comes to COF2 wouldn't all the atoms have a full outer shell by sharing electrons. Sorry I'm just a little confused I'd really appreciate if you could point in the right direction.

Thanks.

Well, the number of electrons is conserved in a neutral molecule.

In order for F to fill it's outer shell, what must happen? Where does the electron originate to fill the p-subshell?

Also, look at the electron configurations of C and O. What must happen for those atoms to fill their p-subshell?

I'm guessing that the electron would originate from the carbon atom.

Carbon needs 4 electrons and oxygen needs 2 electrons in order to fill their p shells. So in this case am I correct in thinking that all the atoms fill their p shells by sharing electrons? If that was the case wouldn't they all have the same electronic configuration as neon since their electronic configuration would be 1s22s22p6? What am I missing?

Thanks.

Looks OK to me.

Try to draw Lewis structure.
