Answer:
Because a molecule, by definition, has a valence of zero
(neutral charge, stable). Also by definition, an ion has a positive
or negative charge or valence and is not stable.
Explanation:
Yes a red blood cell placed in a sline solution shrinks because of the process of osmosis.
The cubic unit cell this metal crystallize as is BCC structure .
<h3>
What is unit cell ?</h3>
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell.
The unit cell consists of lattice points that represent the locations of atoms or ions.
The entire structure then consists of this unit cell repeating in three dimensions

n= 2
Hence our assumption was correct
It is a BCC structure .
Therefore the cubic unit cell this metal crystallize as is BCC structure .
