communicatto
elementfacto: protactinium and their siblings can all sort of make a hivemind with each other. protactinium-230 and protactinium-233 tend to take advantage of this the most
elementfacto 2: most of the actinides refer to protactinium-230 and 230 as “twins”, not for a scientific reason (nor are they actually twins) but its because they are rarely seen without each other (again, not for a scientific reason), so they’re kinda like an inseparable duo
