In crystal of NaCl , consider the particle Cl ⁻ which is present at topmost layer. If x is the number of 2^ nd nearest neighbours and y is the number of 3^ rd nearest neighbours with respect to reference particle. Calculate the value of (x+y) .

Correct answer

12

Step-by-step solution

aligned & x=8 ( at distance a 2 ) & y=4 ( at distance 3 a 2 ) & x+y=12 aligned
