Alright, no Kerbalized names for elements already known to humans. So Kuropium = Europium, Kadmium = Cadmium, Kalcium = Calcium, Karbon = Carbon, etc. Year 3175: It turns out Cadmium (Kadmium) is more likely to combine with Oxygen than not (thus forming Cadmium Oxide, or Cd+2O-2), and as a result many bullets turned to stones that are useless to work with. Kerbals began to turn to Lead (Pb) and laser to create more advanced weapons. Lead work best with gold, which keeps the bullets from rusting and also allow up to 1000 bullets per shot fired launched; while laser creates a very deadly weapon so far: The Laserator (fires up to 100 "bullets" before recharging).
