Calculate the free electron per atom of metal A. The
electrical conductivity of metal A is 6.0 × 10² (N-
m)-¹. The number of free electrons per volume of
metal A is 1.25x102⁹ m ³. Assume that the density
of the metal is 8.9 g/mL and its molar mass is 63.6.
a Spinels are solids with the general formula
M²+ (M¹³+)₂ 04 (where M²+ and M¹³ are
3+
3+
metal cations of the same or different metals).
The best-known example is common magnetite,
Fe3O4 [which you can formulate as
(Fe³+)₂04].
(Fe²+)
A crystal of a spinel
Given its name, it is evident that magnetite is
ferromagnetic. How many unpaired electrons are
there in iron (II) and in iron(III) ions?
Iron(II) ion:
unpaired electron(s)
Iron(III) ion:
unpaired electron(s)
Silicon has a face-centred cubic structure with two atoms per lattice point, just like
diamond. At 25°C, a = 543.1 pm. What is the density of silicon?
