Answer 1

the metal atom is in crystal except murcury

Answer 2

Since the options are given of what kind of answer is expected, I am giving an assumed answer.

The metal atoms in the crystal are in the form of a - structural lattice.

The smallest unit of a crystal is called as the 'unit' which permits identical cells to be stacked together to fill all space. By repeating the pattern of the unit cell over and over again in all the directions, the entire crystal lattice can be constructed.

Crystals are packed in different formats like the hexagonal close packing (HCP), face-centered cubic (FCC) arrangement, and the body-centered cubic (BCC) arrangement.

Crystals can also be formed with three or more elements. Most crystals have only a few atoms per unit cell. Crystals of polymers have thousands of atoms in each unit cell.
