Question

1. What is described by the terms body-centered cubic and face-centered cubic?

O the types of elements that form a crystal
O the crystalline shapes that a metal may be hammered into
the arrangement of atoms or ions in a crystal
the arrangement of crystals in a metal

Answer 1

"The arrangement of atoms or ions in a crystal " is described by the terms body-centered cubic and face-centered cubic.

Step-by-step explanation:

Face centred cubic system explains the crystal structure where an atom is present at each cubic corner of the crystal and the centre of each cube face. Meaningfully, a closed packed plane where at each "face of the cube" atoms touch the alongside face diagonals.

Whereas in body centric cube system has the lattice point present at the 8 corners of cell and an additional one at the center of the cell. Thus, both explains how the atom or ions are placed or arranged in a crystal.
