Discussion Overview

The discussion revolves around whether molecules such as Cl2, O2, and H2 are considered neutral. Participants explore the definitions of "neutral" and "natural," and how these concepts apply to covalently bonded molecules versus ionic compounds.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions if Cl2, O2, and H2 are neutral molecules, noting that their constituent atoms are neutral due to having equal numbers of protons and electrons.
  • Another participant seeks clarification on the definition of "neutral," suggesting that it differs from "natural," and questions whether the molecules fit the definition of neutrality.
  • A participant asserts that covalent bonds are not ionic, providing an example of NaCl as a neutral compound made of ions, while stating that Cl2 is a neutral molecule due to having no net charge.
  • One participant recalls learning that certain elements form diatomic molecules in their natural state and shares a mnemonic for remembering these elements.
  • A repeated inquiry about the terms "neutral" and "natural" indicates confusion over the terminology used in the discussion.
  • Another participant confirms that Cl2 and similar molecules are indeed neutral and mentions checking the neutrality of ozone (O3), which they found to be neutral as well.

Areas of Agreement / Disagreement

Participants express differing views on the definitions of "neutral" and "natural," leading to some confusion. While some assert that the discussed molecules are neutral, others seek clarification on the terminology and the nature of covalent versus ionic bonds. The discussion remains unresolved regarding the precise definitions and implications of neutrality in this context.

Contextual Notes

There is ambiguity in the definitions of "neutral" and "natural," and participants have not reached a consensus on how these terms apply to the molecules in question. The discussion also highlights the distinction between covalent and ionic bonding without resolving the implications for molecular neutrality.

Are Cl2, O2 , H2 etc are nutral molecules?
As we know their atoms are neutral such as Cl. It has 17 protons and 17 electrons. Because it has the equal number of protons and electrons, it is a natural element. But when two Cl atoms combine through covalent bond by sharing a pair of electrons and make Cl2, then is the Cl2 molecule natural as above?

What is the definition of "neutral"? Do these molecules fit that definition?
(BTW, "neutral" means something different from "natural" - or was that just your spellchecker?)

I know that the atoms fit the definition above, but I don't know whether those molecules are neutral or ionic as they all make covalent bonds.
 
A covalent bond is by definition not ionic. For example, NaCl is a neutral compound (no net charge), but it consists of Na+ and Cl- ions in a lattice, without covalent bonds between them. Cl2 consists of discrete molecules containing two chlorine atoms covalently bonded. The molecule has no net charge and is therefore neutral.
 
One of the first things I remember learning in a high school chemistry class, (I subsequently had an advanced high school chemistry class and 3 quarters of university chemistry), is that ## H, O, N, Cl, Br, I,## and ## F ## make diatomic molecules in their natural state. They had us memorize this: HON-Cl-BrIF , and I found it quite useful.

Do you mean "neutral" or "natural"?

I mean 'neutral'

Yes they are neutral. I had to google ## O_3 ##=ozone to see if it was also electically neutral, and that does appear to be the case for ozone as well.
