Bismuth's just a pink poor metal
the least toxic heavy one
you used to use Lead but now me instead
for human interaction

you used to think me stable
but I'm slightly radioactive
so slight my half-life's over
a billion times longer than the age of the universe

Bismuth's a must
for low melting typesetting alloys
Bismuth's from wismuth
German for a mass which is white
denser as a liquid than as a solid mass
expand when I solidify soldering with me's and ideal purpose

Bismuth
