WebAnswer: is If by 21 c your mean 21 - carbon atoms then Number of neutrons for one carbon atom is 6. .. Number of neutrons for 21 carbon atoms = 21 x6 . = 126.. 11) If by 2 1 6 you mean isotope ac, then the question is wrong as 21c does not exists. But, in a hypothetical situation, if a c exists, it implies the mass number ; A = 21. WebCarbon has an atomic number of 6. This means it has 6 protons and 6 electrons.
