Which of the following statements about the interstitial compounds is incorrect?
What are interstitial compounds? Why are such compounds well known for transition metals?
Interstitial compounds are those which are formed when small atoms like, $$H,N$$ or $$C$$ are trapped inside the crystal lattices of metals. They are usually non-stoichiometric and are neither typically ionic or covalent.
Interstitial compounds are well known for transition compounds due to its closed crystalline structure with voids in them. The atomic size of transition metals are very large hence have large voids to occupy these small atoms.
Which of the following statements about the interstitial compounds is incorrect?
Which forms interstitial compounds?
Which of the following statement is not correct?
Interstitial compounds are:
Interstitial compounds are formed when small atoms are trapped inside the crystal lattice of metals. Which of the following is not the characteristic property of interstitial compounds?
In salts of polyatomic anion, as polarising power of cation increases, thermal stability of the salt decreases and decomposed species may further undergo redox reaction. Water soluble salt (x) was heated into three products A,B and C and B and C are two different paramagnetic gases. A is red in hot condition, then salt (x) is
Mercury (II) chloride solution on reaction with gaseous ammonia forms:
When ammonia is added to a cupric salt solution, the deep blue colour is observed it is due to the formation of :
Many transition metals form interstitial compounds. The characteristics of these interstitial compounds are: (I) They have high melting points, higher than those of pure metals (II) They are very hard (III) They retain metallic conductivity (IV) They are chemically more reactive than the pure metals
Which of the following double salt does not exist?
