carbonates. But this loved and popu-
lar character also has some dangerous
properties. Many sodium compounds
are highly water soluble, but if pure
sodium comes in contact with water,
it explodes, proving it to be something
of a gremlin element! That’s why it’s
popular to store it in oil or some other
non-water liquid.

Lighter than aluminum and as strong as
steel, magnesium has good electrical and
magnetic insulation properties and does not
retain heat. That’s why it’s perfect for lap-
top and cell phone shells. But magnesium
is not just a techie element, as it’s found in
abundance both in tofu and in the chloro-
phyll that makes plants green. On top of all
these other talents, its also good for clearing
constipation!

Aluminum is a light metal that’s very easy
to work with. It doesn’t rust, conducts elec-
tricity well, and is extremely cheap. It can
also be alloyed easily to add properties of
other metals, producing things like coins,
aluminum foil, window frames, and airplane
body parts. It has protective properties when
applied to stomach membranes and works
great as a stress reliever—a good thing in
our stress-filled society.

The next time someone asks you about
silicon, just point at some sand. It is the
second most abundant element on Earth
and can be found as silicon dioxide or
silicate in (for example) quartz and crys-
tals. In olden times, it was often used
for making glass due to its strength, but
it’s now the mainstay of the digital age.
We treasure it as vital to creating semi-
conductors and solar batteries. Silicone

Pure silicon isn’t poisonous at all, though.
