Which of the following does not have a hexagonal crystal system?

The parameters of the unit cell of a substance are $a=2.5, b=3.0, c=4.0, \alpha=90^{\circ}, \beta=120^{\circ}, \gamma=90^{\circ}$. The crystal system of the substance is :

Chromium metal crystallises in a body-centred cubic $(bcc)$ lattice. The edge length of the unit cell is found to be $287 \, pm$. The atomic radius of chromium will be ............. $pm$.

For an orthorhombic crystal system,the axial lengths are $a \neq b \neq c$. What are the axial angles?

The crystal system with edge lengths $a \neq b \neq c$ and axial angles $\alpha = \beta = \gamma = 90^{\circ}$ is '$x$' and the number of Bravais lattices for it is '$y$'. $x$ and $y$ are:

Determine the Miller indices for the plane $\left( -a, 2b, \infty \right)$.
