What is the formula of a compound formed by imaginary atoms A and B. A

1.	What is the formula of a compound formed by imaginary atoms A and B. Atom A belongs togroup 2 and atom B is a non-metal with valency 2. (Explain the reason for your answer)
Answer» Answer: Correct option isB AB2 Atom 'A' at FCC lattice points MEANS NUMBER of atom A in UNIT cell is: 81×8+ 21×6=4. If in a close-packed structure (CCP or fcc) there are 'n' atoms or ions then the number of tetrahedral voids will be 2N. Thus the number of atom B is =2×4=8 Thus the compound is A4B8 or AB2 Option B is correct

Answer»

Answer:

Correct option isB

AB2

Atom 'A' at FCC lattice points MEANS NUMBER of atom A in UNIT cell is:

81×8+ 21×6=4.

If in a close-packed structure (CCP or fcc) there are 'n' atoms or ions then the number of tetrahedral voids will be 2N. Thus the number of atom B is =2×4=8

Thus the compound is A4B8 or AB2

Option B is correct
