Recall that in one mole of a substance there are an Avogadro number of molecules. That is:
therefore, in 1.2 g, there would be ten times less molecules than in the 12.0 g mole, that is: molecules.
Now, each C there are 6 negative charges, then, the number of electrons will be six times the number of C molecules, that is:
Now we multiply this number times the charge of an electron , and we obtained the total negative charge of the carbon sample:
Total negative charge is:
therefore the total negative charge is: -57792 C
carbon contains 6 protons, 6 electrons as well as 6 neutrons
Every carbon atom has six protons, and the majority of carbon atoms have six neutrons. A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes.
