It is doubtful that there are gases in the atmosphere that are foreign to us here on earth. It is made up of about 90% hydrogen, close to 10% helium with the rest Consisting of ammonia, sulfur, methane and water vapor.
How do we know this? There could be gases underneath the atmosphere that we cannot detect or wouldn't know about due to our tech.
I've read about the H3 moon mining talks. I think it was either, Japan, Russia or Elon Musk(lol).

There's always a possibility of finding gasses that we don't know about, but since we are just exploring a planet in our solar system, I think it would be very low percentage.

Any gas we encounter will still be just isotopes of hydrogen and helium etc. There are no undiscovered light elements and we will never discover another one. These elements fall on the periodic scale based on how many protons it has. Hydrogen has one proton and uranium has much more for example. Everything we encounter with one proton is still hydrogen. We already know how any undiscovered element will behave and it will be heavy and only live a fraction of a second.
We know what makes up the planet by analyzing its spectrum and other high tech devices at our disposal. The Galileo mission in the 90's dropped a titanium probe into the atmosphere giving us firsthand knowledge of its contents. We know its mass by looking at the orbit of its moons and how fast they orbit. Closer to a likely solid core the hydrogen and helium are in a liquid like state due to pressure.
