元素の周期的分類
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their…
原子半径と有効核電荷
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same…
イオン半径
Ionic radius is the measure used to describe the size of an ion. A cation always has fewer electrons and the same number of protons as the parent…
イオン化エネルギー
The amount of energy required to remove the most loosely bound electron from a gaseous atom in its ground state is called its first ionization energy…
電子親和力
The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion). This process can be…
アルカリ金属
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of…
ハロゲン
Group 17 elements, known as halogens, are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine a solid.…
希ガス
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they…
固定化金属アフィニティークロマトグラフィーにおける金属浸出の定量
Contamination of enzymes with metals leached from immobilized metal affinity chromatography (IMAC) columns poses a major concern for enzymologists,…
分子から素材まで: ハロゲン結合を介して新しいイオン液体結晶工学
Herein, we demonstrate that a bottom-up approach, based on halogen bonding (XB), can be successfully applied for the design of a new type of ionic…
F<sup>−</sup> 310 Nm 剥離によって示されている陰イオンの光電子イメージング
Anion photoelectron imaging is a very efficient method for the study of energy states of bound negative ions, neutral species and interactions of…
