2023年6月30日 — Sodium chloride crystals are brittle ... Brittleness is again typical of ionic substances. Imagine what happens to the crystal if a stress is ...
Caesium chloride or cesium chloride is the inorganic compound with the formula CsCl. This colorless salt is an important source of caesium ions in a variety ...
2021年11月19日 — Ionic compounds are also brittle. Brittleness means that one layer of the crystal lattice can slip over another when it is hit with a physical ...
It also explains why caesium chloride has a different structure from sodium chloride even though sodium and caesium are both in Group 1 of the Periodic Table.
We'll look first at the arrangement of the ions and then talk about why the structures of sodium chloride and caesium chloride are different afterwards.
2017年5月11日 — They are hard because of strong electrostatic forces between atoms. They are brittle because of low mobility of defects called dislocations ...
2017年6月27日 — Many metal oxides are pretty dense. Heavy alkali halides, such as caesium iodide are reasonably dense for definitely ionic. Density depends on ...
