| Manganese (Mn) is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties. Steelmaking, including its ironmaking component, accounts for most domestic manganese demand, presently in the range of 85% to 90% of the total. Manganese ferroalloys, consisting of various grades of ferromanganese and silicomanganese, are used to provide most of this key ingredient to steelmaking. Products for construction, machinery, and transportation are leading end uses of manganese. Manganese also is a key component of certain widely used aluminum alloys and, in oxide form, dry cell batteries. As ore, additional quantities of manganese are used for such nonmetallurgical purposes as plant fertilizers, animal feed, and colorants for brick. |

Einsteinium was discovered by a team of scientists led by Albert Ghiorso in 1952 while studying the radioactive debris produced by the detonation of the first hydrogen bomb. The isotope they discovered, einsteinium-253, has a half-life of about 20 days and was produced by combining 15 neutrons with uranium-238, which then underwent seven beta decays. Today, einsteinium is produced though a lengthy chain of nuclear reactions that involves bombarding each isotope in the chain with neutrons and then allowing the resulting isotope to undergo beta decay.
A poem about...
Einsteinium
by Joe Davis
Einsteinium must have been named after Einstein
Inventor of many things and discoverer of even more
Nuclear energy and the nuclear bomb
So was space and the meaning of it
Two hundred and fifty four is the R.A.M. of Einsteinium
Einsteinium is the 99th element in the periodic table
It is in the f-block along with :
Nobelium, thorium, fermium
It is also with
Uranium and
Mendelevium
