Fact-check: Five claims about thorium made by Andrew Yang

Claim: Next generation thorium reactors would be safer than current reactors. True but misleading. Nuclear energy is already very safe, and Yang is correct about that. The current US nuclear fleet generates about 20 percent of all electricity in the United States and has an excellent safety record—despite accidents such as Three Mile Island.

Thallium – Wikipedia

Im Gegensatz zu den leichteren Gruppenmitgliedern kommt Thallium überwiegend in der Oxidationsstufe +I vor. Dies ist auf den thermodynamischen 6s-Inertpaar-Effekt zurückzuführen, da die Ionisierungsenergie der 6s-Elektronen anormal hoch ist. Die Oxidationsstufen +II und +III sind auch möglich, jedoch wesentlich seltener vorzufinden.
