Did you know?
Diamonds and graphite are both made of pure carbon — just arranged differently.
Did you know?
Diamonds and graphite are both made of pure carbon — just arranged differently.
Which is the incorrect statement?
Density decreases in case of crystals with Schottky’s defect.
NaCl(s) is an insulator, silicon is a semiconductor, silver is a conductor, quartz is a piezoelectric crystal.
Frenkel defect is favored in those ionic compounds in which sizes of cation and anions are almost equal.
FeO has non-stoichiometric metal deficiency defect.
To determine the incorrect statement, let's analyze each option:Option 1:Schottky defect involves the loss of equal numbers of cations and anions from the lattice,which decreases the density of the crystal. This statement is correct.Option 2:NaCl is an insulator because it does not conduct electricity in solid form.Silicon is a semiconductor, as it has a band gap that allows it to conduct electricity under certain conditions.
