Chemical bonding,any of the interactions that account for the association of atoms into molecules,ions,crystals,and other stable species that make up the familiar substances of the everyday world.When atoms approach one another,their nuclei and electrons interact and tend to distribute themselves in space in such a way that the total energy is lower than it would be in any alternative [2002.04611] The role of delocalized chemical bonding in Feb 11,2020 Classification of chemical bonds based on topological#0183;Principles that predict reactions or properties of materials define the discipline of chemistry.In this work we derive chemical rules,based on atomic distances and chemical bond character,which predict topological materials in compounds that feature the structural motif of a square-net.Using these rules we identify over 300 potential new topological materials.We show that simple chemical [2002.04611] The role of delocalized chemical bonding in Feb 11,2020 Classification of chemical bonds based on topological#0183;Principles that predict reactions or properties of materials define the discipline of chemistry.In this work we derive chemical rules,based on atomic distances and chemical bond character,which predict topological materials in compounds that feature the structural motif of a square-net.Using these rules we identify over 300 potential new topological materials.We show that simple chemical

What Can Tell the Topological Analysis of ELF on Hydrogen

The topological analysis of the electron localization function (ELF) provides a convenient mathematical framework enabling an unambiguous characterization of bonds,and more particularly in terms of bond types.In this communication we present an overview of the application of this approach to hydrogen bonding in which we attempt to answer the following questions 1.Types of Chemical Bonds Chemistry [Master]Chemical bonds This pictures shows examples of chemical bonding using Lewis dot notation.Hydrogen and carbon are not bonded,while in water there is a single bond between each hydrogen and oxygen.Bonds,especially covalent bonds,are often represented as lines between bonded atoms.Acetylene has a triple bond,a special type of covalent bond Types of Chemical Bonds Chemistry [Master]Chemical bonds This pictures shows examples of chemical bonding using Lewis dot notation.Hydrogen and carbon are not bonded,while in water there is a single bond between each hydrogen and oxygen.Bonds,especially covalent bonds,are often represented as lines between bonded atoms.Acetylene has a triple bond,a special type of covalent bond
