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 ...

2019年6月5日 — The attractions are less between the bigger ions and so less heat energy is needed to separate them. Sodium chloride crystals are brittle.

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 ...

The electrostatic repulsion can be enough to split the crystal, which is why ionic solids are brittle. MORE INFO.
