Im building a carbon atom. I’ve been told that the atomic number of carbon is 6, which means that the carbon Atom has how many protons. The carbon atom I’m building has a total of 12 particles in it nucleus, which means that I need to use how many neutrons. The carbon atom I’m building has 6 electrons. These electrons are found in levels. The first level of the carbon atom has how many electrons, and the second level has how many electrons.
