Essentially, the assembly -- known from Sept. 20, 1792, on as the National Convention -- split into two major factions: the moderate Girondins and the radical Jacobins (the most prominent of whom was Robespierre).On the city streets of Paris, another political faction was gaining steam.he National Assembly was born out of shared interest in liberty, equality and brotherhood, but as the French Revolution wore on, differences in political ideologies became more obvious.
Carbon-12 is the most common isotope of carbon. Carbon-14 is radioactive and very rare. Carbon-14; 8 neutrons Carbon-13; 7 neutrons Carbon-12; 6 neutrons The symbols for the isotopes of carbon atoms shown here indicate they each have six protons but mass numbers of 14, 13 and 12. These isotopes are not equally abundant.Carbon-12 (C-12) makes up 98.9 % of all carbon atoms while carbon-13 (C-13) makes up 1.1 %.n example of this is shown with the three different isotopes of carbon. Here they all have 6 protons, but different numbers of neutrons. Carbon-14 has 8 neutrons. Carbon-13 has 7 neutrons and carbon-12 has 6 neutrons.
For example, the most common isotope of carbon is carbon-12, or 12C, which has 6 protons and 6 neutrons. The full isotope symbol would also have the atomic number (Z) as a subscript to the left of the element symbol directly below the mass number: 12 6C.
