A two-dimensional solid pattern formed by two different atoms X and Y is shown below. The black and white squares represent atoms X and Y , respectively. The simplest formula for the compound based on the unit cell from the pattern is
Options
- AXY ₈
- BX₄ Y₉
- CXY ₂
- DXY ₄
Correct answer
A. XY ₈
Step-by-step solution
The unit cell of the above pattern will consist of 8 white square and 1 black square i.e. it will form centre unit cell. No. of white square Y =8 No. of black square X=1 Formula X Y _ 8
