What is atomic radius in chemistry?
Atomic radius: The radius of an atom. This distance between an atom’s nucleus and outer electron shell. (This is not a fixed entity, so there are numerous definitions of this term, depending upon the measurement used.)
What is 92 on the periodic table?
Uranium
Uranium is a silver-gray metallic chemical element in the actinide series of the periodic table that has the symbol U and atomic number 92. Uranium has the highest atomic weight of the naturally occurring elements.

What is 93 on the periodic table?
neptunium
Between those planets sits Neptune, and the gap between the two elements leaves a space for their relatively unsung cousin, neptunium – element number 93 in the periodic table.
What is the chemical symbol of yttrium?
YYttrium / Symbol
What is the atomic number of yttrium?
Chemically, yttrium resembles those elements more closely than its neighbor in the periodic table, scandium, and if physical properties were plotted against atomic number, it would have an apparent number of 64.5 to 67.5, placing it between the lanthanides gadolinium and erbium.
What is the most stable isotope of yttrium?
Isotopes and nucleosynthesis. At least 32 synthetic isotopes of yttrium have been observed, and these range in atomic mass number from 76 to 108. The least stable of these is 106 Y with a half-life of >150 ns ( 76 Y has a half-life of >200 ns) and the most stable is 88 Y with a half-life of 106.626 days.
Is yttrium a heavy lanthanide?
Yttrium is so close in size to the so-called ‘yttrium group’ of heavy lanthanide ions that in solution, it behaves as if it were one of them. Even though the lanthanides are one row farther down the periodic table than yttrium, the similarity in atomic radius may be attributed to the lanthanide contraction.
What is the difference between yttrium and zirconium?
Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “rare-earth element”. Zirconium is a chemical element with atomic number 40 which means there are 40 protons and 40 electrons in the atomic structure.
