What is Superactinide?
The '''superactinides''' are a group of hypothetical [[chemical element|elements]] that are predicted to be elements 121-156. One of these elements is expected to have a magic number of [[protons]] and [[neutrons]] which is [[unbihexium]]. An [[isotope]] of unbihexium is expected to have 126 protons and 184 neutrons. Before the Superactinides, there are [[Ununennium]] and [[Unbinilium]]. As of 2024, none has been found. The elements in this block are considered to be as g-block elements. ==Superactindes== === Unbiunium === Further Information: [[Unbiunium]] [[File:Electron shell 121 Unbiunium.svg|thumb|Bohr model of Unbiunium]] Unbiunium, also known as eka-[[actinium]], was attempted to be synthesized in 1977 by shooting Copper-65 at Uranium-238. It was unsuccessful and no atoms were identified. ===Unbibium=== Further Information: [[Unbibium]] [[File:Electron shell 122 Unbibium.svg|thumb|Bohr model of Unbibium]] Unbibium, also known as eka-[[thorium]], was attempted to be synthesized in 1972 by shooting Zirconium-66 and 68 at Uranium-238. It was unsuccessful and no atoms were detected. Unbibium is predicted to be in the [[island of stability]]. ===Unbitrium=== Further Information: [[Unbitrium]] [[File:Electron shell 123 Unbitrium.svg|thumb|Bohr model of Unbitrium]] Unbitrium also known as eka-[[protactinium]], or element-123. No attempt has ever been made to make Unbitrium. ===Unbiquadium=== Further Information: [[Unbiquadium]] [[File:Electron_shell_124_Unbiquadium_-_no_label.svg|thumb|Bohr model of Unbiquadium]] Unbiquadium, also known as eka-[[uranium]], is the predicted element-124. It is predicted that Unbiquadium-308 has a magic number of neutrons, 184. It is in the [[island of stability]]. === Unbipentium === Futher Information: [[Unbipentium]] [[File:Electron shell 125 Unbipentium.svg|thumb|Bohr model of Unbipentium]] Unbipentium also known as eka-[[neptunium]], is the predicted element-125. In 1977, Unbipentium was tried to be synthesized by shooting [[zinc]]-68 and 68 at [[americium]]-238. It was
