Why uncharged atoms or molecules never crystallize in simple cubic structures?
Uncharged molecules and atoms are packed more efficiently in closed-packet structures. Hence theses uncharged molecules and atoms do not crystallize in simple cubic structures.
How many liters in 2.73 cubic meters?
1 cubic metre = 1000 litres so 2.73 cubic metres = 2730 litres. Simple!
How many atoms are there in 13 moles of bromide?
If you think to a simple binary bromide as NaBr: 166,57.10e23 atoms.
How many electrons are in Polonium?
Polonium is simple cubic. each corner is 1/8 atom. simple cubic has 8 corners therefore: (1/8) x 8 = 1 atom/unit cell. Polonium is simple cubic. each corner is 1/8 atom. simple cubic has 8 corners therefore: (1/8) x 8 = 1 atom/unit cell.

What is the lowest and highest number of shared and unshared atoms in a unit cell of a FCC structure and a simple cubic structure?
Your question, if I understand it correctly, asks to explain the reasoning behind the coordination number, or number of adjacent atoms, of an atom in a simple cubic structure versus an atom in a face centered cubic structure (FCC).Before we proceed, I would like to clarify one thing:A unit cell of a simple cubic crystal has 1 atom, while a unit cell of FCC crystal has 4 atoms. This may be a little counterintuitive at first, but consider how the atoms are shared. For the simple cubic structure, there are eight individual atoms - one at each corner of the cube. The unit cell, however, has to share each atom with the 8 other adjacent cells. Thus a unit cell gets 8 atoms only 1/8 of the time, hence 8*(1/8) = 1 atom per simple cubic unit cell. Similarly, FCC has the 1 atom from simple cubic, plus half of the 6 atoms on each of it's faces. Thus, FCC has 4 atoms per unit cell.On to the main question. In short, given a homogeneous, perfect crystal the coordination numbers of all the atoms are the same. All atoms are shared equal with their neighbors.For the simple cubic case this is easy to see. Like the simple gumdrop creations of second graders, you can start at any gumdrop to make the creation. Any corner is the same relative to its neighbors as any other corner. For FCC the same is true.
How many mercury atoms are in 7.6 cubic centimeters of liquid mercury?

Simple cubic body-centered cubic and face-centered cubic unit cells all have the same shape How are they different?
They differ in the number of atoms within the unit cell. Body-centered contains two atoms, face centered contains four. Images online or in textbooks show this best.
How many atoms are humans made out of?
Simple Answer: A LOT!
What is close pack?
Another way of describing the arrangement of atoms is by identifying layers. In the hexagonal close pack, the base layer consists of six atoms in a hexagon around a central atom. The next layer is the same, but it is stacked above the first layer by having the atoms nestle in the spaces between atoms. The third layer is like the first, and so on. This structure allows the atoms to fill the available volume very effectively, much more so than the simple cubic structure. This is why very few atoms form solids with simple cubic unit cells but very many have the hexagonal close pack structure. cobalt is an example of a hexagonal close pack solid.
How many cubic meters in 70 liters?
1 litre = 0.001 cubic metres so 70 litres = 0.07 cubic metres. Simple!
How many liters in 2.73 cubic meters?
1 cubic metre = 1000 litres so 2.73 cubic metres = 2730 litres. Simple!
