Discussion Overview

The discussion revolves around determining the number of electron shells in noble gas elements, specifically helium, neon, argon, and radon, using the periodic table as a reference.

Discussion Character

  • Conceptual clarification

Main Points Raised

  • One participant expresses confusion about how to find the number of shells for noble gases and questions if the periodic table is the right resource.
  • Another participant suggests that the number of completed shells corresponds to the element's position on the periodic table, indicating that helium has 1 shell, neon has 2, and argon has 3.
  • A further contribution includes a link to a Wikipedia page that illustrates electron configurations, implying it may help clarify the topic.

Areas of Agreement / Disagreement

There is no clear consensus on the method for determining the number of shells, as participants provide differing levels of detail and clarity in their responses.

Contextual Notes

The discussion does not address potential limitations in the periodic table's representation of electron shells or the specific configurations of radon.

I am confused? Do I look at somewhere on the periodic table? For example for the noble gas items argon, radon, helium, and neon?

I hope that I posted this in the right section as well..
 
If you look at the periodic table, then the number of completed shells corresponds to the order as you go down the list. Helium - 1, Neon - 2, Argon - 3, etc.
 
See http://en.wikipedia.org/wiki/Electron_configuration" . The first illustration shows what you are interested in. Note the specific elements you want are along the right edge.
