]L's+"Xenon"?


The missing elements are Darmstadtium, Praseodymium, Protactinium and Rutherfordium which are 12 or 13 characters long which means I can't print them in 13 characters each.

The idea is that the first few programs, which prints the elements with short names use their extraneous characters to build the string Chuck Norri in the variable L, which does not affect the output when used on their own. The final program then checks if anything is already on the stack, and uses it to choose between L (plus s) and Xenon.

A few additional bytes are saved by using the character we just added to L as part of the element name, specifically for Carbon, Nickel, Copper and Silver.
