Witryna4 lip 2024 · All the defects and impurities described for metals are seen in ionic and molecular compounds as well. Because ionic compounds contain both cations and anions rather than only neutral atoms, however, they exhibit additional types of … WitrynaThere are two types of impurity defects, they are: Interstitial impurity defect (according to these defects, compounds have tetrahedral or octahedral holes into atoms) …
Witryna25 mar 2024 · In NaCl, due to a non-stoichiometric defect, an electron occupies an interstitial position and when it is excited, it imparts colour. Complete answer: ... Point defects are further classified into stoichiometry defects, impurity defects and non-stoichiometric defects. Sodium chloride can show all of these defects but the … Witryna4 kwi 2024 · Both the type of point defects can be seen in NaCl, (a) stoichiometric defect : The Schottky defects are seen in NaCl. The defects are created when the same number of C l − and N a + is missing from their position in the lattice and creating holes. Even after missing some ions, it will be electrically neutral. (b) Non …
Witryna18 mar 2024 · When NaCl is doped with SrCl 2, it leads to an impurity defect. Impurity defect is defined as a defect which arises when a foreign atom replaces a host atom at the lattice site. The process of adding impurities to the crystal is known as doping. In the given case, to maintain electrical neutrality, each Sr 2+ ion replaces two Na + ions.
WitrynaIn case of ionic compounds, the impurity 1S also ionic in nature. When the impurity has the same charge as the host ion. it just substitutes some of the host ions. Impurity defects can also be introduced by adding impurity ions having different charge than host ions. e.g. molten NaCl containing a little amount of SrCI 2 is crystallised.
