oxygen
oxygen is the most used element in the periodic table because we use it to breath and to make carbon dioxide (CO2) when we breath out.
80%Hydrogen (H2)19%Helium1.5%Methane
Not counting the Noble Gases in the last group of the Periodic Table, the most active elements are located at the lower left and upper right. Assuming you are talking about pure, elemental gases, that would make Fluorine the most active gas.

The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
no - gases are few in number - metals make up most of the periodic table
Nope. Nitrogen (70%) is the most common, followed by Oxygen (26%). Carbon dioxide makes up less then 0.04% of the air we breath.

Most planet's atmosphere's contain poisonous gases, and non in our solar system contain oxygen.
These gases are nitrogen, oxygen and argon.
oxygen is the most used element in the periodic table because we use it to breath and to make carbon dioxide (CO2) when we breath out.
Yes it is a mixture of nitogen, 80% oxygen 18% and carbon dioxide and other gases 2 % Intrestingly humans breath in then breath out most of the taken oxygen in each breath, only consuming a small percentage, thus we can reveive someone using mouth to mouth resusitation.
Oxygen and nitrogen are the two most abundant gases in the atmosphere. They make up 99% of the air.
yes they are acually the most important the make the air we breath it
When inhaling, you are taking in the air that surrounds us. This air is composed of several gases, of which oxygen is the most important to us. When we exhale, we breath out mainly carbon dioxide, and any other gases that we don't need to use.
most of what you breath in is a greenhouse gas (eg: carbon dioxide, water vapour), so nothing, infact you need some GHG's to survive.
