I have heard that amongst the people who actually mine the ore, the name is “Molly-be-damned” rather than the tongue-twisting actual name of Molybdenum (42)! Never found pure and its ores are easily confused with elemental Lead (82) but since its identification and refinement, Molybdenum is a prime alloy with steel for hardness and armor-plating.
It’s funny that the Veritasium guy uses “42” as his “element of truth”.
