Choose the correct statement/s:a)Orthorhombic has maximum number of Br...
Orthorhombic has maximum number of Bravis lattices:
The statement is correct. The Bravis lattices are the possible arrangements of points in a crystal lattice that maintain translational symmetry. There are 14 possible Bravis lattices, and the orthorhombic crystal system has the maximum number of Bravis lattices. The orthorhombic system has three mutually perpendicular axes of different lengths, resulting in eight possible lattice types.
Monoclinic is the least symmetric crystal system:
The statement is incorrect. The least symmetric crystal system is the triclinic system, not the monoclinic system. The triclinic system has no symmetry elements, whereas the monoclinic system has a single twofold rotation axis, resulting in a higher degree of symmetry compared to the triclinic system.
For a bcc unit cell, unoccupied space is about 31.98%:
The statement is correct. In a body-centered cubic (bcc) unit cell, the packing efficiency, which is the ratio of the volume of the atoms to the total volume of the unit cell, is approximately 68%. This means that about 32% of the unit cell is unoccupied space. The bcc unit cell consists of eight corner atoms and one atom in the center of the unit cell.
Si group 15 element gives p-type semiconductor:
The statement is incorrect. Silicon (Si) is a group 14 element, not a group 15 element. Group 15 elements, such as nitrogen (N), phosphorus (P), and arsenic (As), have five valence electrons and can act as donors in a semiconductor, leading to n-type conductivity. Silicon, on the other hand, has four valence electrons and can either act as an intrinsic semiconductor or be doped to create either p-type or n-type conductivity.
The statement is correct. The Bravis lattices are the possible arrangements of points in a crystal lattice that maintain translational symmetry. There are 14 possible Bravis lattices, and the orthorhombic crystal system has the maximum number of Bravis lattices. The orthorhombic system has three mutually perpendicular axes of different lengths, resulting in eight possible lattice types.
Monoclinic is the least symmetric crystal system:
The statement is incorrect. The least symmetric crystal system is the triclinic system, not the monoclinic system. The triclinic system has no symmetry elements, whereas the monoclinic system has a single twofold rotation axis, resulting in a higher degree of symmetry compared to the triclinic system.
For a bcc unit cell, unoccupied space is about 31.98%:
The statement is correct. In a body-centered cubic (bcc) unit cell, the packing efficiency, which is the ratio of the volume of the atoms to the total volume of the unit cell, is approximately 68%. This means that about 32% of the unit cell is unoccupied space. The bcc unit cell consists of eight corner atoms and one atom in the center of the unit cell.
