1}^{\,\,\,\,0}\textrm{e}\) Carbon-14 is a radioactive isotope of carbon. Each atom has six protons and eight neutrons. It decays to form nitrogen, which has seven protons and seven neutrons.

Once collected, the leaves were analysed in the lab for the presence of different isotopes of nitrogen. An atom consists of a nucleus containing particles called protons and neutrons. Around this ...

If an atom has 2 protons, that’s an atom of the element helium. If it has 7 protons, that’s nitrogen. But the logic of the periodic table also relies upon the number and organisation of electr ...
