<span>I am a Carbon atom and I took birth in the air. I had spend a memorable time in a molecule and there were two very nice oxygen atoms too. I just got into the air and I am very excited that I had my complete incoming box of electrons. I am a carbon atom and I have six electrons. Right now I am in a carbon dioxide molecule and I am just wondering in air. While i was enjoying my journey I waved to my friends like oxygen gas which is a molecule of two oxygen atoms.Oxygen atom is my best friend. I’ve heard stories of becoming solids and many different things when i was too young, but now I just like the air and I am loving it.</span>
