Oxygen, Nitrogen, Carbon Dioxide and Argon.
I'm afraid that the Earth's early atmosphere was made up of Ammonia, Water vapour, Carbon monoxide, Methane, Sulphur dioxide, Helium, Carbon Dioxide, Nitrogen & a few other gases.
Comments number 1 & 3 are wrong because it's asking for Earth's EARLY atmosphere but there was no Oxygen in Earth's EARLY atmosphere!!
argon
Yes. All naturally occurring elements in the universe can be found in most stars, though generally only in small concentrations. Massive stars that have depleted the hydrogen in their cores may start producing elements as heavy as iron.
Fumaroles are formed only when steam and hot gases are expelled from small vents, usually found on volcanoes.
Every day, you breathe nitrogen and oxygen along with many other gases. Helium is inert and poses no threat at all except if you breathe only helium and you deprive yourself of oxygen. In theory, any gas can be breathed in small concentrations since the concentration is what determines hazardous effects. Even Oxygen can kill you if it is in too high of a concentration.
They do not exist in a stable natural state. They had to be made by man in the same way as many of the Actinides This is wrong. Unlike most actinides, they all exist as stable isotopes and some are reasonably common. The main reason is that they are very chemically similar to one another and thus are hard to isolate as pure elements. this is rite...
Atmosphere contains roughly (by volume) 78.09% nitrogen, 20.95%oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases.

well sea water that comes from the atmosphere contains small concentrations of the gases in the atmosphere such as oxygen, carbondioxide, carbonmonoxide, and nitrogen. it would also contain pollutants from factories
Yes. Most of the greenhouse gases do occur naturally, particularly carbon dioxide (CO2). By maintaining the temperature that we enjoy today, these gases are essential to life on earth as we know it, as long as the concentrations of the gases do not rise or fall appreciably. In the absence of human activity the concentrations of greenhouse gases remain more or less constant over time, so that there is no effect on global warming. However, when human activity results in even a small increment in the concentrations of greenhouse gases, we begin to get global warming and climate change.
Radium exist in very small concentrations in some meteorites.
PPM is an acronym for parts per million, a term for quantifying small concentrations of substance in gases, liquids, or solids.
Ozone is an allotrope of oxygen which is found mainly in the stratospheric region. Some small concentrations of ozone are also present in the tropospheric region but the concentrations are of the level of parts per million so the concentrations are mainly neglected.
PPM stands for parts per million when reporting very small concentrations
Radium exist only in very small concentrations in uranium and thorium ores; radium hasn't its own minerals.

Air isn't a pure substance, it is a mixture of a bunch of other gases mainly Nitrogen and Oxygen with small amounts of other gases.
