In the unit cell of galena, six square faces of equal size each form 90 degree angles with every adjacent face. What type of cry

lbvjy [14]

Answer : The correct option is, Cubic.

Explanation :

As there are seven types of crystal systems which are cubic, tetragonal, orthorhombic, monoclinic, triclinic, rhombohedral and hexagonal.

A unit cell is characterized by the axial length (a, b and c) and axial angle $(\alpha ,\beta ,\gamma )$ parameters which decide the size and shape of the unit cell.

In tetragonal crystal system, $a=b\neq c$ and $\alpha=\beta=\gamma=90^o$

In hexagonal crystal system, $a=b\neq c$ and $\alpha=\beta=90^o,\gamma=120^o$

In triclinic crystal system, $a\neq b\neq c$ and $\alpha\neq \beta\neq \gamma=90^o$

In cubic crystal system, $a=b=c$ and $\alpha=\beta=\gamma=90^o$

Hence, the correct option is, Cubic.
