Describe the crystal structure of Pt, which crystallizes with four equivalent metal atoms in a cubic unit cell

Short Answer

Expert verified

The crystal structure of Pt is face centered cubic structure.

Step by step solution

01

To describe the crystal structure of Pt

In this case, each of the eight corners of a cube has one-eighth platinum atom and each of the six faces has\(\frac{1}{2}\)Pt atom.

\({\rm{ Total = }}\frac{{\rm{1}}}{{\rm{8}}}{\rm{ \times 8 + }}\frac{{\rm{1}}}{{\rm{2}}}{\rm{ \times 6 = 4}}\)

Hence Platinum forms a face centered cubic structure.
