Capitolo 8
Classificazione periodica degli elementi
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their…
Raggi atomici e carica nucleare efficace
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same…
Raggi ionici
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…
Energia ionizzata
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…
Affinità elettronica
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…
Metalli alcalini
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of…
Alogeni
Group 17 elements, known as halogens, are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine a solid.…
Gas nobili
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they…
Quantificazione della lisciviazione dei metalli nella cromatografia di affinità metallica immobilizzata
Contamination of enzymes with metals leached from immobilized metal affinity chromatography (IMAC) columns poses a major concern for enzymologists,…
Dalle molecole ai materiali: nuovi cristalli liquidi ionici attraverso legame alogeno di ingegneria
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…
Imaging di fotoelettroni di anioni illustrato da 310 Nm distaccamento di 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…
