In NaCl structure, `Cl^-` ions have ccp arrangement and `Na^+` ion occupy all the octahedral site. The total number of `Na^+` and `Cl^-` ions per unit cell is:

What are the coordination number of Na^+ and Cl^- ions in NaCl?

In a structure, A atoms have fcc arrangement B atoms occupy all the tetrahedral sites and C atoms occupy half the octahedral sites. what is the formula of the compound ?

In crystal structure of sodium chloride, the arrangement of Cl ions is

True or false Number of Na^+ and Cl^- ions in a unit cell are 6 and 6 respectively.

In corrundum, oxide ions are arranged in hcp arrangement and the aluminium ions occupy 2/3 of the octahedral voids. What is the formula of corrudum?

The questions given below consist of an assertion and the reason. Use the following key to choose the appropriate answer. (a) Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion. (b) The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.(c) Assertion is is CORRECT but reason is INCORRECT. (d) If assertion is INCORRECT but reason is CORRECT. (e)If both assertion and reason are INCORRECT. Assertion: In CaF_2, F^- ions occupy all the tetrahedral sites. Reason: The number of Ca^(2+) is double the number of F^- ions.
