What is the chemical symbol for ruthenium?
The chemical symbol for Ruthenium is Ru. Mass numbers of typical isotopes of Ruthenium are 98-102. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A.
Is ruthenium a rare metal?
Ruthenium is a chemical element with symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table. Ruthenium is generally found in ores with the other platinum group metals in the Ural Mountains and in North and South America.
How many stable isotopes of ruthenium are there?
Naturally occurring ruthenium is composed of seven stable isotopes. Additionally, 34 radioactive isotopes have been discovered. Of these radioisotopes, the most stable are 106Ru with a half-life of 373.59 days, 103Ru with a half-life of 39.26 days and 97Ru with a half-life of 2.9 days.
What is the intermolecular structure of ruthenium?
Such weak intermolecular bonds give organic molecular substances, such as waxes and oils, their soft bulk character, and their low melting points (in liquids, molecules must cease most structured or oriented contact with each other). A possible crystal structure of Ruthenium is hexagonal close-packed structure.
