I previously asked a broad enough question about designing a fictional gas but it was advised by two users to split it into smaller questions. So here I am.
The main property I want this gas to have is an incompatibility with electricity so that enough of an electrical reaction could lower its quality, push it away, or simply render it unusable. Any of these is okay. A hypothetical creature that needs to breathe that gas to live would get sick, or die if it was too dependant on the gas/weak enough.
What I mean by polluting or lowering the quality of the gas, is this: the air we humans need can easily be made unbreathable or difficult to breathe by smoke. Something similar would happen to this gas, but with electricity. A lightning strike could, for example, charge the gas in a way that makes it highly volatile.
'Electricity' here means visible sparks, lightning shocks, and electric fields.
Is this scientifically possible? How?
