Comments
Quote: "Except for dubnium, even the longest-lasting isotopes of transactinide elements have extremely short half-lives, measured in seconds, or smaller units."
Also, given the immense instability that permeates the series, "transactinides" is probably more of a primary category for these elements than "transition metal", "post-transition metal", "metalloid", or "noble gas" would be. After all, most inorganic chemistry texts I have seen cover the elements beyond Lr (the last of the actinides) all together, instead of with their respective groups.

I have just added archive links to one external link on
Transactinide element. Please take a moment to review
my edit. If necessary, add {{
cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

Transactinide element →
Superheavy element – Most articles seem to use the term superheavy element more frequently than transactinide element to refer to the (same) set of elements with atomic number ≥ 104. While transactinide element is certainly still used, a Google Search shows that superheavy element is 5-10 times more popular, while it is about three times more popular in Google Scholar. This shifting usage is especially noticeable in more recent articles describing the island of stability and undiscovered elements, so I feel this article title should reflect what is most commonly used in reliable sources. Also note that this move is technically limited because
superheavy element is a redirect with non-trivial history; if consensus is reached, an administrator will need to execute the move.

Support. During my work on these elements individually, I have seen the scientists involved use the suggested term much more commonly than the old one. My understanding based on what I've read over these years is that there is a slight change in what the accent is put on between the two terms, with "superheavy elements" originally being a more nuclear-related term but now being increasingly more general, whereas "transactinide element" is becoming more specialized on the chemical aspect of it. Chemistry is very interesting indeed but does not dominate the discussions as the nuclear properties are also of the highest interest.--

Compounds
I'm writing a binder of elements and I'm noticing that my superheavy section is quite bare. Is there any super heavy element compounds that we know of?

Sure, some chemistry is known till Hs, and somewhat sketched out for Cn through Fl. You'll probably have to wait a while for much more.

In general people (ab)use "lighter" and "heavier" to mean atomic number rather than relative atomic mass. But I'm fine with this change for clarity.
