No, the most abundant element on earth by mass is oxygen.
We know that nitrogen (at about 78%) and oxygen(at about 20 %) are the most abundant gases in the atmosphere. By inspection, it's obvious that there is only a couple of percent for all the other gases combined.
Carbon dioxide (CO2) is the molecule that carries most of the carbon in the atmosphere.
The most polar bond would be between carbon and fluorine. Fluorine is the most electronegative element, creating a large electronegativity difference with carbon and resulting in a highly polar bond.
Carbon-12 is the most abundant isotope of carbon, making up about 98.9% of carbon found in nature. Carbon-13 is the second most abundant isotope, making up about 1.1% of natural carbon.
Carbon is a non metal element. Mass number of it is 12.
