There's an unleaded avgas available that got FAA approval last year. With how slowly aviation moves it may take another 10 years before lead gas gets replaced completely.

Reply to comment by Ishana92 in Why not use hydrogen and deuterium in fusion reaction rather than tritium and deuterium? by Curious_user4445
Just like electrons have orbital shells that affect chemical stability, the nucleus has quantum states with different binding energies. In general even numbers of protons and neutrons are higher binding energy that odd numbers. Helium 4 is particularly high binding energy, as it is double magic.
