Ionic Radii03:10

Ionic Radii

33.5K
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 atom; it is smaller than the atom from which it is derived. For example, the covalent radius of an aluminum atom (1s22s22p63s23p1) is 118 pm, whereas the ionic radius of an Al3+ (1s22s22p6) is 68 pm. As electrons are removed from the outer valence shell, the remaining core electrons occupying smaller shells experience a greater effective nuclear...

Ionic Bonds

Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Molecular and Ionic Solids

20.1K
Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...

Solubility of Ionic Compounds02:55

Solubility of Ionic Compounds

68.2K
Solubility is the measure of the maximum amount of solute that can be dissolved in a given quantity of solvent at a given temperature and pressure. Solubility is usually measured in molarity (M) or moles per liter (mol/L). A compound is termed soluble if it dissolves in water.

Ionic Crystal Structures02:42

Ionic Crystal Structures

17.0K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Ionic Compounds: Formulas and Nomenclature

87.3K
An element composed of atoms that readily lose electrons (a metal) can react with an element composed of atoms that readily gain electrons (a nonmetal) to produce ions through complete electron transfer. The compound formed by this transfer is stabilized by the electrostatic attractions (ionic bonds) between the oppositely charged ions.

Area of Science:

  • Materials Science
  • Computational Chemistry
  • Condensed Matter Physics

Background:

  • Ionic liquids (ILs) exhibit unique properties tunable by cation and anion choice.
  • Understanding the relationship between IL structure and mechanical properties is crucial for material design.
  • Molecular dynamics (MD) simulations offer a powerful tool to probe these relationships at the atomic level.

Purpose of the Study:

  • To calculate high-frequency elastic moduli of 1-alkyl-3-methylimidazolium-based ionic liquids.
  • To evaluate the heterogeneity of local elastic moduli and its correlation with structural features.
  • To assess the influence of alkyl chain length and anion type on elastic properties.

Main Methods:

  • Performed molecular dynamics (MD) simulations on five ionic liquids with varying alkyl chain lengths and anions ([NO3]- and [PF6]-).
  • Obtained dispersion curves for longitudinal and transverse acoustic modes from mass current time correlation functions.
  • Calculated local bulk and shear moduli by applying deformations to systems cooled to 0 K.

Main Results:

  • High-frequency sound velocity of longitudinal acoustic (LA) modes depends on alkyl chain length, while transverse acoustic (TA) modes do not.
  • High-frequency bulk (K) and shear (G) moduli are influenced by alkyl chain length (density effect) and strongly depend on the anion.
  • Increasing alkyl chain length in [C_nC1im][NO3] leads to nano-heterogeneous structures with lower local moduli in non-polar domains.
  • Replacing [NO3]- with [PF6]- reduces the mean value and standard deviation of local elastic moduli distributions.

Conclusions:

  • Structural heterogeneity in ionic liquids, particularly domain segregation due to alkyl chains, directly impacts local elastic moduli.
  • The choice of anion plays a significant role in determining both the overall and local elastic properties of ionic liquids.
  • MD simulations provide valuable insights into the structure-property relationships governing the mechanical behavior of ionic liquids.
