Another project along the same lines as "Ammonia". This one gets kinda repetitive because of all the information that had to be included.

This one was made with Famitracker and the VRC7 expansion.

Lyrics:

[Refrain]:
Thallium!
Number 81!
It was used in a number of poisioning murders in Australia!
(repeat once)

[Verse 1]:
Thallium
Gray in isolation
But it becomes discolored when it is exposed to any oxygen
Thallium
Its group is the thirteenth one
It shares the boron family with gallium and aluminum
Thallium
Its noble gas configuration:
Xenon 4f14 3d10 6s2 6p1
Thallium
Its radius: 170 pm
It may be larger than most of its group, but it's small within its period

[Refrain]

[Bridge]:
Ionization energy
is 589.4
Which in this case is measured in kilojoules
times moles to the negative one
That value is larger than most in its period
but smaller than most in its group
But it's still...
fairly reluctant to give up electrons

[Refrain]

[Verse 2]:
Thallium
Its compounds are of interest to some
Such as thallium sulfate, which was used as poison
to control rodent populations
Thallium sulfide
was used in early film projectors
Thallium bromide
is used in gamma ray detectors
Thallium oxide
makes a glass with refractive index so very hi-igh
but if you're looking for a fungici-ide
go with thallium carbonate

[Refrain]

Thallium!
