Nucleons are the particles that make up the nucleus of an atom. That means protons and neutrons. The number of nucleons here would be 12 because the 6 protons and 6 neutrons add up to 12 nucleons.
Fourteen, the sum of 6 and 8. The mass of electrons is so small compared with protons and neutrons that electron mass is ignored in mass number calculations.
carbon-14 (the sum of six and eight)
14.
The isotope carbon-12 has 6 protons, neutrons and electrons.
Carbon has 6 protons, 6 electrons, and 6 neutrons because 12.011 is rounded to 12.000 so 12.000-6=6 so 6 neutrons.
The natural isotope of carbon 13C (abundance 1,1 %) has 6 protons, 6 electrons and 7 neutrons.
The isotope carbon-40 doesn't exist !
Only carbon has 6 protons. Specifically, this is a neutral atom of the isotope 12C.
The isotope carbon-12 has 6 protons, neutrons and electrons.
For the isotope carbon-12: 6 protons, 6 neutrons, 6 electrons
The isotope carbon-16 has 6 protons and electrons and 10 neutrons.
Carbon has 6 protons, 6 electrons, and 6 neutrons because 12.011 is rounded to 12.000 so 12.000-6=6 so 6 neutrons.
The natural isotope of carbon 13C (abundance 1,1 %) has 6 protons, 6 electrons and 7 neutrons.
The isotope 12C has 6 protons, neutrons and electrons.
To know the element, you need only know how many protons it has. All atoms of carbon have 6 protons. Carbon-12 is an isotope of carbon that has 6 protons and 6 neutrons.
The isotope carbon-40 doesn't exist !
There would be 6 protons and 5 neutrons. Such isotope does not exist though.
Only carbon has 6 protons. Specifically, this is a neutral atom of the isotope 12C.
All the chemical elements contain atoms; and each atom is formed from protons, neutrons, electrons. The most abundant carbon isotope - 12C - has 6 protons, neutrons and electrons.
For the isotope carbon-12: 6 neutrons, 6 protons, 6 electrons
