Ionic Radii03:10

Ionic Radii

33.3K
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...

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.

Polymers

40.5K
The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Ionic Compounds: Formulas and Nomenclature

86.2K
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.

Molecular and Ionic Solids

20.0K
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

68.1K
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.

Area of Science:

  • Materials Science
  • Polymer Chemistry
  • Nanotechnology

Background:

  • Development of porous materials for gas storage is crucial.
  • Ionic porous polymers offer tunable properties for specific applications.
  • Boronate-based polymers are emerging as promising candidates.

Purpose of the Study:

  • To synthesize novel boronate-type ionic porous polymers.
  • To investigate their gas sorption properties, particularly for H2 and N2.
  • To evaluate the impact of structural modifications on material performance.

Main Methods:

  • Polycondensation reactions of lithium tetrakis(4-boronatoaryl)borates with polyhydroxyl monomers.
  • Characterization using PXRD, MAS NMR (6Li and 11B), FT-IR, SEM, and TGA.
  • Gas sorption analysis (H2 and N2 uptake).

Main Results:

  • Successfully synthesized four boronate-type ionic porous polymers (TAB1-4).
  • Achieved good hydrogen sorption capacity (up to 75 cm3/g STP).
  • Observed relatively poor nitrogen sorption at low pressures (up to 50 cm3/g STP below P/P0 = 0.8).
  • Elongating aryl arms negatively impacted sorption characteristics.

Conclusions:

  • The synthesized polymers demonstrate potential for hydrogen storage.
  • Nitrogen sorption performance needs further optimization.
  • Aryl arm length is a critical factor influencing the gas sorption capabilities of these materials.
