{'tritium': [0, 0, 1, 1], 'protons': [0, 0, 0, 1], 'neutrons': [0, 0, 1, 1]}
The correct answer is option 2, which states that Tritium (T) has 1 proton (P) and 2 neutrons (N).
Tritium is an isotope of hydrogen, which means it has the same number of protons as hydrogen (1) but a different number of neutrons. While hydrogen typically contains no neutrons, tritium contains two additional neutrons.
To summarize, the nucleus of tritium consists of 1 proton and 2 neutrons, giving it a total mass of approximately 3 atomic mass units.
