Question

Most closely packed structure is

Answer 1

Answer:

most closely packed is solid

Answer 2

Answer:

The face-centered cubic lattice is most closely packed.

Explanation:

There are three types of cubic crystals. Which are as follows:-

(a)Face centered cubic lattice

• They have 4 atoms per unit cell.
• They have a packing efficiency of 74%.

(b)Body-centered cubic lattice

• They have 2 atoms per unit cell.
• They have a packing efficiency of 68%.

(c)Simple cubic lattice

• They have 1 atom per unit cell.
• They have a packing efficiency of 52.5%.

We can see that face-centered cubic lattice has the highest packing efficiency. Hence, the face-centered cubic lattice is most closely packed.
