What is the term for the repeating pattern in a crystalline structure? a) Repeating pattern
b) Base pattern
c) Unit cell
d) Primitive pattern

Because a crystalline solid consists of repeating patterns of its components in three dimensions (a crystal lattice), we can represent the entire crystal by drawing the structure of the smallest identical units that, when stacked together, form the crystal. This basic repeating unit is called a unit cell.Aug 12, 2020

I think option c (unit cell) is the correct answer..

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
