WebApr 5, 2024 · carbon (C), nonmetallic chemical element in Group 14 (IVa) of the periodic table. Although widely distributed in nature, carbon is not particularly plentiful—it makes up only about 0.025 percent of Earth’s crust—yet it forms more compounds than all the other elements combined. WebThe discovery of isotopes. Evidence for the existence of isotopes emerged from two independent lines of research, the first being the study of radioactivity. By 1910 it had become clear that certain processes associated with radioactivity, discovered some years before by French physicist Henri Becquerel, could transform one element into another ...
WebJul 4, 2024 · The element carbon (C) has an atomic number of 6, which means that all neutral carbon atoms contain 6 protons and 6 electrons. In a typical sample of carbon-containing material, 98.89% of the carbon atoms also contain 6 neutrons, so each has a mass number of 12. WebWhat differences exist between different isotopes of an element? (Two points) ... Carbon, for instance, is made up of three different isotopes: carbon-12 (12C), carbon-13 (13C), and carbon-14 (14C) (14C). The atomic number of each of these isotopes is 6, although their mass numbers vary greatly from one another (12, 13, and 14 respectively). ...
