Question

A compound forms hexagonal close-packed structure. What is the total
number of voids in 0.5 mol of it? How many of these are tetrahedral voids?​

Answer 1

Answer:

Answer

Number of atoms in close packaging = 0.5 mol

1 has 6.022×10

23

particles

So that

Number of close-packed particles

=0.5×6.022×10

23

=3.011×10

23

Number of tetrahedral voids = 2 × number of atoms in close packaging

Plug the values we get

Number of tetrahedral voids =2×3.011×10

23

=6.022×10

23

Number of octahedral voids = number of atoms in close packaging

So that

Number of octahedral voids =3.011×10

23

Total number of voids = Tetrahedral void + octahedral void

=6.022×10

23

+3.011×10

23

=9.03×10

23

Answer:

diagonal relationship is said to exist between certain pairs of diagonally adjacent elements in the second and third periods of the periodic table. These pairs exhibit similar properties; for example, boron and silicon are both semiconductors, forming halides that are hydrolysed in water and have
