  Mendelevium - Wikipedia, the free encyclopedia
Mendelevium (also known as unnilunium, Unu) is a synthetic element in the periodic table with the symbol Md (formerly Mv) and the atomic number 101.
A metallic radioactive transuranic element of the actinides, mendelevium is synthesized by bombarding einsteinium with alpha particles and was named after Dmitri Mendeleev.
Mendelevium (for Dmitri Mendeleyev, surname commonly spelt as Mendeleev, Mendeléef, or even Mendelejeff, and first name sometimes spelt as Dmitry or Dmitriy) was first synthesized by Albert Ghiorso (team leader), Glenn T. Seaborg, Bernard Harvey, and Greg Choppin in early 1955.

 Physical and Chemical Properties of Mendelevium - Periodic Table of the Elements
Mendelevium is the ninth transuranium element of the actinide series.
Experiments indicate that mendelevium has a moderately stable dipositive (II) oxidation state in addition to the tripositive (III) oxidation state, as is characteristic of the actinide elements.
Mendelevium first was produced during the bombardment of Es-253 with helium ions in the Berkeley 60-inch cyclotron.

Mendelevium is a metal of the actinide series in group IIIb of the periodic table.
Mendelevium-256 (half-life about 76 min) was the first isotope produced; it was detected in 1955 by Albert Ghiorso, Bernard G. Harvey, Gregory R. Choppin, Stanley G. Thompson, and Glenn T. Seaborg, who produced it one atom at a time by bombarding einsteinium-253 with alpha particles in a cyclotron at the Univ. of California at Berkeley.
This technique of producing and detecting single atoms has become the standard for the discovery of the elements beyond mendelevium in the periodic table.

 Facts about Mendelevium
Mendelevium classified as an element in the Actinide series as one of the "Rare Earth Elements" which can located in Group 3 elements of the Periodic Table and in the 6th and 7th periods.
Mendelevium was first synthesized in the USA by Albert Ghiorso (team leader), Glenn T. Seaborg, Bernard Harvey, and Greg Choppin in 1955.

The name and symbol Mendelevium (Md) was ratified by the International Union of Pure and Applied Chemistr (IUPAC) Council meeting in Geneva during August 1997 (see below).
With this table the properties of missing elements were forecast, and chemists began to appreciate it when the discovery of elements predicted by the table took place.
This is despite the fact that the original Swedish claim to have prepared element 102 was subsequently shown to have been in error by the Dubna laboratory, which finally achieved an undisputed synthesis.

 mendelevium
Not occurring in nature, mendelevium (as the isotope mendelevium-256) was discovered (1955) by Albert Ghiorso, Bernard G. Harvey, Gregory R.
In about a dozen repetitions of the experiment, the team of scientists produced 17 atoms of mendelevium, which were identified by the ion-exchange adsorption-elution method (mendelevium behaved like its rare-earth homologue thulium).
Studied by means of radioactive tracer techniques, mendelevium exhibits a predominant +3 oxidation state, as would be expected by its position in the actinide series; a moderately stable +2 oxidation state is also known.

Mendelevium's most stable isotope, mendelevium-258, has a half-life of about 51.5 days.
Since only small amounts of mendelevium have ever been produced, it currently has no uses outside of basic scientific research.

Initially it was not detected any alpha particle activity that could indicate the presence of element 101; however, spontaneous fission of fermium was observed leading to a new element, proved in subsequent experiences to be the 101st.
Based on this evidence, although indirectly, the investigators announced the discovery of element 101, suggesting the name mendelevium, in honor of Dimitri Mendeleev.
Originally, the symbol of the mendelevium was Mv, this being later altered to the actual Md.

The isotope produced was 256Md, which has a half-life of 78 min.
It now appears possible that eventually enough 258Md can be made so that some of its physical properties can be determined.

Far from our nightmare vision of poorly written advertising by a flaky group of unqualified idealists, we found that real world applications were available that performed more than adequately.
This is not the most exciting introduction available to the field of Mendelevium advertising.
Real-world focus—with examples, issues, and applications interlaced throughout—improves this introduction to both the theory and practice of Mendelevium, and it does provide important insights into how advertising is done, but the critical questions must be resolved.
