The atomic number of carbon is 6. What is the mass number of a carbon atom with 5 neutrons? What is the atomic number for carbon dioxide? What is the mass number for carbon? What is the nucleon number of carbon 14? What is the atomic number of oxygen-16?
Atomic mass is a number that represents the amount of matter in an atom or isotope of a certain element, specifically the number of protons and neutrons. Atomic mass is calculated as an average mass of the different isotopes of each element. The unit for atomic mass is ''amu,'' which ...
The mass difference of the seven mass peaks is 14鈥塧mu possibly because of the number of bound CH2 and nitrogen atom. These mass spectra are not found by analyzing other carbon specimens such as carbon nanotubes, graphite, and graphens. Uniqueness of the mass spectra could be due to the ...
