Most carbon atoms have six positively charged protons and six uncharged neutrons.Since protons and neutrons weigh about the same, the atomic mass of ordinary carbon is 6 6 = 12.

Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.So, we rely on radiometric dating to calculate their ages.The fact that it has seven protons is what makes it nitrogen.Other atoms are also named based on the number of protons they carry.
