Element 211? What's the half-life of that?

[pozorvlak]

I was wondering when someone would ask that :-) Most isotopes are stable, but there's one with a half-life of 170 years.

You may wish to have another look at the numbers in lines 4 and 5 :-)

Spoiler

If 211 is trinary, it comes out to (9 * 2) + (3 * 1) + 1 = 22. Element 22 is titanium.

Unless the digits are in right to left order, in which case it's 2 + (3 * 1) + (9* 1) = 14. Element 14 is Silicon, which is a sensible answer. It also makes lines 4-5 lists of the first few prime numbers :)

Very good. And the half-lives of titanium and silicon are? :-)

[strawberryfrog]

.. are easy to look up. Silicon matches what you said, Ti doesn't.
