List of top Chemistry Questions on Unit Cells asked in AP EAPCET

A compound is formed by \(A\) (cations), \(B\) (cations) and \(O\) (anions). Atoms of \(O\) form a ccp lattice. Atoms of \(A\) occupy \(50\%\) of octahedral voids and atoms of \(B\) occupy \(25\%\) of tetrahedral voids. What is the molecular formula of the compound?
Given below are statements
Statement I: Unit cell in a lattice has six characteristic parameters
Statement II: In fcc lattice, the total number of atoms/ions per unit cell is 4
The fraction of the total volume occupied by the atoms present in a face centred cubic unit cell is
Metals A and B crystallize in "simple cubic" and "face centered cubic" lattice respectively. The number of metal atoms A and B per unit cell are respectively:
A cubic lattice has atoms of A at the body centre, atoms of B at the corners of the cube and atoms C at all the face centres. What is its formula?
