2.Isotopes of Carbon.
The carbon element has three isotopes having the same atomic number of 6 but different mass numbers of 12,13 and 14.The three isotopes of carbon can be written as :
C C C
These three isotopes of carbon contain 6 protons and 6 electrons each but they contain an unequal number of neutrons. The C-12 isotope contains 12-6 = 6 neutrons, C-13 isotope contains 13 - 6 = 7 neutrons whereas the C-14 isotope contains 14 - 6 = 8 neutrons.
