Osmium, Cesium, and Xenon! Heavy stuff, explosive stuff, and bright stuff. I've got a soft spot for heavy elements...

Americium.
USA! USA!
Nah, just kidding. Though it is somewhat special to me, as I chose to make a model of it in 7th grade when everyone had to make a 3-D Bohr model for a
project. I chose it because it's the biggest one that still has a practical everyday use (smoke detectors).
Really though I haven't picked a favorite. The periodic table is such a wonderful place with so many unique characters that as soon as I feel like I
have a favorite element another one takes its place!

One element that consistently stays one of my favourites is osmium. It's the densest element, being almost two times denser than lead, and it's a blue
metal, which is just flat out awesome. It's tetroxide is also a pretty transparent greenish colour, but it's ridiculously toxic. Oh well, osmium is
still amazing

I thought that only osmium tetroxide is toxic, and because osmium forms the tetroxide in air, it is always toxic.

No, the tetroxide only forms in air when the osmium is a finely divided powder. If you have a nice chunk of it it's perfectly harmless. (I would love
to have a nice chunk of osmium… that would be really cool)

Osmium awesomeness:
Heating osmium chunks to 400 degrees C will cause them to start producing the tetroxide. The tetroxide is yellowish because some is reduced back to
osmium dioxide.
Silicon is a pretty cool element - it's so light and shiny. It would probably be good for jewelry, but it's too brittle. I'd also like some indium,
that way I could bend and scratch metal with my bare hands. Or some europium for its fluorescence: red in the trivalent state, blue in the divalent
state. Or some rhodium - because it's rare and I could sell it for a big profit. 
At the end of the day, simulating atoms doesn't beat working with the real things...

Hmmm..
Carbon, bismuth, and silicon. I'm sure this will end up changing eventually but I think carbon will always be my number 1.
Love the way those osmium crystals look. Shame about osmium compounds toxicity I'd love to acquire some of the raw element for a collection.

Alright, I will admit that those are beautiful crystals. But I'll take rhodium, iridium, ruthenium, or even rusty iron over osmium any day.

Rhodium, iridium, and ruthenium I can understand. But rusty iron?? Why?

Bismuth. I think this was always a foregone conclusion.
Although, rusty iron is also nice.

Aw man I completely forgot about bismuth. Hopper crystals are awesome. I read that if you leave the iridescent crystals in nitric acid, the iridescent
layer disappears. A tin impurity will prevent it from forming at all.
Anyone know any brands of fishing weights that contain bismuth?

Almost all of the "Bio Friendly" ones do.

Most all of them...
Sorry, I just can't choose a favorite. I like most all of them for various reasons. Whether it's the super reactivity of F or the inertness of Xe,
the rarity of Pt/Au/Pd, the toughness of the transition metals (in alloys), and the uniqueness of just about every one I can see on the periodic
chart. Can't say I know much about elements with atomic numbers 105 and up, but when I looked at the chart as a kid they weren't there, so they are
all the more mysterious. Nope, can't decide on a favorite, too many lovely elements!

Xe is not inert.

compound to be synthesized. |

Everything is relative. Xe is relatively inert, just as I would refer to other noble gases and some elements as "inert". N2 is relatively inert, but
there are many N compounds. I had watched that neat old video posted by plante1999 on Xe reactivity before I posted, so I knew some Xe compounds
could be formed when I referred to it as inert.
But I still can't decide on a favorite. Maybe silver, iodine, strontium, chlorine, and of course xenon would be near the top of my list.

You tell 'em 
Yea, strontium is probably one of my favorites too Strontium nitrate was the first oddball chemical I ever got, which triggered me buying way too much
barium nitrate later on in life (I hate having large quantities of poisons).
