Question

Copper has face centered cubic (fcc) lattice with interatomic spacing equal to 2.54Å. The value of lattice constant for this lattice is-

Answer 1

Answer :- 3.59 Å

Consider the lattice parameter as a. Let r be intra atomic spacing.

Since we have face centered cubic here :-

a = √2 x r

In the given question , r = 2.54 Å

a = √2 x 2.54 Å

a = 3.59 Å

Hence the value of lattice constant for this lattice is 3.59 Å.

Answer 2

Copper has face centred cubic (FCC) lattice with interatomic spacing equal to 2.54 A.

The value of the lattice constant for this lattice is 3.59 Å hope it is right answer for the student to get best solution for your entire problem.

You can simply calculate with the given value and formula with no risk and trouble of it.
