The synthetic elements are those with atomic numbers 95–118, as shown in purple on the accompanying periodic table: [1] these 24 elements were first created between 1944 and 2010. The mechanism for the creation of a synthetic element is to force additional protons into the nucleus of an element with an atomic number lower than 95.
Potassium hydroxide is an inorganic compound with the formula K OH, and is commonly called caustic potash. Along with sodium hydroxide (NaOH), KOH is a prototypical strong base. It has many industrial and niche applications, most of which utilize its caustic nature and its reactivity toward acids.
2 KMnO 4 + 16 HCl → 2 MnCl 2 + 5 Cl 2 + 2 KCl + 8 H 2 O. In neutral solution, permanganate slowly reduces to manganese dioxide (MnO 2). This is the material that stains one's skin when handling KMnO 4. KMnO 4 reduces in alkaline solution to give green K 2 MnO 4: [75] 4 KMnO 4 + 4 KOH → 4 K 2 MnO 4 + O 2 + 2 H 2 O

A steel bottle containing MgCp 2 (magnesium bis-cyclopentadienyl), which, like several other organometallic compounds, is pyrophoric in air.. Organometallic compounds are distinguished by the prefix "organo-" (e.g., organopalladium compounds), and include all compounds which contain a bond between a metal atom and a carbon atom of an organyl group.

Lutetium compounds are compounds formed by the lanthanide metal lutetium (Lu). In these compounds, lutetium generally exhibits the +3 oxidation state, such as LuCl 3, Lu 2 O 3 and Lu 2 (SO 4) 3. [1] Aqueous solutions of most lutetium salts are colorless and form white crystalline solids upon drying, with the common exception of the iodide.
Potassium iodate (K I O 3) is an ionic inorganic compound with the formula KIO 3. It is a white salt that is soluble in water. ... friction, [4] combustible materials ...
Hassium is a synthetic chemical element; it has symbol Hs and atomic number 108. It is highly radioactive: its most stable known isotopes have half-lives of about ten seconds. [a] One of its isotopes, 270 Hs, has magic numbers of protons and neutrons for deformed nuclei, giving it greater stability against spontaneous fission.
