Update:

Ruthenium: Hrærekssilfur (Ruthenium was called after an old name for Russia. Why not naming the element after the founder of the Russian nation, Rurik (Icelandic: "Hrærekur"). Many element were named after individuals.

Uranium: ýmisefni, aurgelmisblý (One could name uranium after the equivalent of Uranus in Nordic mythology: Ýmir (or "Aurgelmir"). The construction Aurgelmisblý sound-similar to uranium in the first syllable. Because the element was named after the planet Uranus and not after the god, after whom the planet was named, it would be appropriate to use Aurgelmir for the gas-giant too.

Tantalum: Tálvonarglit (Tálvonarlegur (tantalizing) + glit (metallic lustre)

Lathanides: "Lotuþribblingar" or "lotujarðmálmur": þribbil (element in group 3B: þrí- + B +-ill)

Hafium: Hafnarþungsteinn (hafnar- refering to Copenhagen, þunsteinn (wolfram)

Wolfram: Vargfróðumálmur (an alternative, after "wolfram" (the froth of a wolf, because tungsten-containing scheelite devoured tin in the smelter)

Titanium: Forguðamálmur (forguð= preguðir (pre-gods, the Titans were the Elder gods or "pre-gods" in Greek Mythology)

Krypton: stikuloft (Once krypton was used to exactly establish the length of a metre)

Nobelium: Elfráðsblý (the shortest construction (Elfráður (Alfred (Alfred Nobel) + blý (lead))

Europium: Eftnumálmur (Eftna = Europe (i-shit of "aftan" (evening), the "Evening" land, German "Abendland", Icel. kvöldlönd, Kvöldálfa, Kvoldmeginland, but the shortest construction is "Eftna", which is as short as the second name for Europa in the Snorra Edda (Enea). It's best to keep the name feminine like Evrópa. Other derivation from "aftan": Eftningur (European), Afneskur (European), Aftnesku bandalagið (European Union), or "Eftningabandalagið".

Sulphur: Múspellshallur (synonym, "Múspell" was the "Mordor" in Nordic Mythology.
