סיווג מחזורי של יוסודות
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their…
רדיוס אטומי ומטען גרעיני אפקטיבי
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same…
רדיוס יוני
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…
אנרגיית יינון
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…
זיקת אלקטרונים
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…
מתכות אלקעליות
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of…
הלוגנים
Group 17 elements, known as halogens, are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine a solid.…
גזים אצילים
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they…
קוונפיקציה של מתכת Leaching ב קיבוע מתכת זיקה כרומטוגרפיה
Contamination of enzymes with metals leached from immobilized metal affinity chromatography (IMAC) columns poses a major concern for enzymologists,…
ממולקולות חומרים: הנדסה בגבישים נוזליים יוניים חדש דרך הלוגן מליטה
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…
Photoelectron הדמיה של אניונים מאויר על ידי ניתוק 310 ננומטר F<sup>−</sup>
Anion photoelectron imaging is a very efficient method for the study of energy states of bound negative ions, neutral species and interactions of…
