Clasificación Periódica de los Elementos
The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their…
Radio Atómico y Carga Nuclear Efectiva
The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same…
Radio Iónico
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…
Energía de Ionización
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…
Afinidad Electrónica
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…
Metales Alcalinos
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of…
Halógenos
Group 17 elements, known as halogens, are nonmetals. At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine a solid.…
Gases Nobles
The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they…
Cuantificación de la lixiviación de metal en la cromatografía de afinidad de metal inmovilizada
Contamination of enzymes with metals leached from immobilized metal affinity chromatography (IMAC) columns poses a major concern for enzymologists,…
De las moléculas a los materiales: Ingeniería nuevos cristales líquidos iónicos a través de la vinculación de halógeno
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…
La proyección de imagen del fotoelectrón de aniones ilustrado por 310 Nm la separación de 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…
