oxygen
Oxygen was least likely to have been a component of Earth's atmosphere before life began. It was initially scarce, and the atmosphere was primarily made up of gases such as methane, ammonia, water vapor, and carbon dioxide. Oxygen started to accumulate in the atmosphere following the emergence of photosynthetic organisms.
The primary gases in Earth's primitive atmosphere were likely hydrogen, helium, methane, ammonia, and water vapor. Over time, these gases were likely transformed by geological and biological processes into the current composition of the atmosphere.
The main component of Earth's original atmosphere was likely hydrogen and helium. Over time, these gases were largely lost to space, and the atmosphere evolved to primarily consist of nitrogen and oxygen as a result of volcanic outgassing and the development of life on Earth.
The most likely gas present in Earth's earliest atmosphere was likely hydrogen, along with some helium. This was later followed by the emergence of volcanic activity that released gases such as water vapor, carbon dioxide, and nitrogen. Oxygen was not a major component of the early atmosphere.
Argon is a noble gas and does not react with other elements in the atmosphere, so it has remained relatively constant over time. The initial percentage of argon in the Earth's atmosphere was likely determined by the gases present during the planet's formation. The lack of significant processes that remove or add argon to the atmosphere has helped to maintain its percentage over time.

The gas you are referring to is likely nitrogen. Nitrogen is the most abundant component of Earth's atmosphere, making up approximately 78% of the air we breathe. It is colorless, odorless, and mostly inert.

If Earth did not have any life, its atmosphere would likely consist mostly of nitrogen, similar to the atmosphere of Mars or Venus. Volcanic activity would have likely contributed to the release of gases like carbon dioxide and water vapor. Sunlight and cosmic rays might also have influenced the composition of the atmosphere over time.
If a component is hooked into a live circuit, it is likely that the component itself will be damaged.
The Earth's atmosphere began forming approximately 4.5 billion years ago during the Hadean Eon, following the planet's formation. This initial atmosphere was likely composed of gases released from volcanic activity and impacts from comets and asteroids.
Earth's atmosphere formed around 4.5 billion years ago, shortly after the planet's formation. The early atmosphere likely consisted of gases such as hydrogen and helium, but has since evolved through volcanic activity and the presence of living organisms to the composition we see today.
The main component of Earth's ancient atmosphere was likely carbon dioxide (CO2), which was released by volcanic activity. Over time, photosynthetic organisms like cyanobacteria helped to transform CO2 into oxygen through the process of photosynthesis, leading to the development of Earth's current atmospheric composition.
