Formula of Magnetic Oxide of Cobalt
The formula of the magnetic oxide of cobalt used in recording tapes is CoO2.
Crystallisation Pattern
The magnetic oxide of cobalt crystallises in a closest packed array of oxide ions, with cobalt atoms occupying one-eighth of the tetrahedral holes and one-half of the octahedral holes.
Explanation
The closest packed array of oxide ions is a crystal structure in which the oxide ions are arranged in a manner that maximises their packing density. In this structure, the cobalt atoms occupy one-eighth of the tetrahedral holes, which are the spaces between four oxide ions arranged in a tetrahedral shape. The cobalt atoms also occupy one-half of the octahedral holes, which are the spaces between six oxide ions arranged in an octahedral shape.
The formula of the magnetic oxide of cobalt is CoO2 because each cobalt atom occupies one-eighth of a tetrahedral hole and one-half of an octahedral hole. Therefore, the ratio of cobalt atoms to oxide ions is 1:2, which corresponds to the formula CoO2.
Conclusion
The magnetic oxide of cobalt used in recording tapes has a formula of CoO2 and crystallises in a closest packed array of oxide ions, with cobalt atoms occupying one-eighth of the tetrahedral holes and one-half of the octahedral holes. This structure maximises the packing density of the oxide ions and allows for efficient magnetic recording.
