What are the uses of 256 MD of mendelevium?
Since only small amounts of mendelevium have ever been produced, it currently has no uses outside of basic scientific research. 256 Md has been used to elucidate some of the chemical properties of mendelevium in aqueous solution. See more information at the Mendelevium compound page.
How many protons are in the nucleus of mendelevium?
Mendelevium is a chemical element with atomic number 101 which means there are 101 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
