How do you get 99 Molybdenum?
Mo-99 is produced in the uranium-bearing targets by irradiating them with thermal neutrons. Some of the U-235 nuclei absorb these neutrons, which can cause them to fission. The fission of the U-235 nucleus produces two but sometimes three lower-mass nuclei referred to as fission fragments.

What is TA periodic table?
tantalum (Ta), chemical element, bright, very hard, silver-gray metal of Group 5 (Vb) of the periodic table, characterized by its high density, extremely high melting point, and excellent resistance to all acids except hydrofluoric at ordinary temperatures.
What is Rh on the periodic table?
rhodium (Rh), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, predominantly used as an alloying agent to harden platinum. Rhodium is a precious, silver-white metal, with a high reflectivity for light.
What does atomic number 73 mean?
tantalum, Ta, atomic number 73 (noun) a hard grey lustrous metallic element that is highly resistant to corrosion; occurs in niobite and fergusonite and tantalite.
What are elements numbers?
The 100 or so elements are listed by #Z_”the atomic number”#. #”Z=1, hydrogen; Z=2, helium; Z=3, lithium; …..Z=92, uranium..”#. And by definition, #Z# represents the number of MASSIVE, POSITIVELY charged particles, i.e. nuclear protons, that are present in the element’s nucleus, and #Z# thus defines the IDENTITY of the given nucleus.
How do you calculate atomic number of an element?
Locate the element’s atomic number. The atomic number is located above the element symbol, in the upper left-hand corner of the square. The atomic number will tell you how many protons make up a single atom of an element. For example, boron (B) has an atomic number of 5, therefore it has 5 protons.
What element has an atomic number of 78?
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile , highly unreactive, precious, silverish-white transition metal. Its name is derived from the Spanish term platino, meaning “little silver”.
