What contains a structure called a nucleus?
Every cell and atom has a nucleus.
What is a unit cell?
The unit cell is defined as the smallest geometric repetition of an which gives actual crystal structure is known as unit cell
What is a face centered cubic crystal?
A face-centered cubic unit cell is a cube. All sides are the same length and all face perpendicular to each other, with an atom at each corner and an atom in the middle of each face of the cell.

What is the chromosomal structure that limits the number of cell divisions of a cell?
Telomeres
What is the simplest repeating unit of crystal structure?

What is the difference between face centered cubic crystal structure and hexagonal close pack crystal structure?
face centre cubic crystal has eight atoms in each corner and one atom in the centre of cubic unit cell.while hexagonal close packed structuree has only six atoms in corners but no in the centre of cubic cell
Which series shows the level of organisms in order from the smallest to the largest structure?
atom, molecule, cell, organiism
Number of atoms in hcp unit cell?
"There are 6 atoms in the hcp unit cell. The hex shape has six atoms at the points that are direct translations of each other making 1 atom for the top hex and one atom for the bottom hex. That's 2. The atom in the center of the top and center of the bottom are translations giving 1 more. That's 3. Then there are 3 atoms in the middle region of each cell bringing the total to 6." The answer should depend on how you choose your unit cell. In the primitive hexagonal cell we have 1 atom at each of the corners of the cell (each is "worth" 1/8) and 1 atom within the cell giving us 2 atoms/unit cell. (Note: the 'primitive hexagonal cell' above actually refers to the parallelpiped structure that the hexagonal unit cell consists of: the hexagonal 'unit' -it cannot technically be referred to as a unit cell, because unit cells are the most reduced form of the crystal structure- can be divided into 3 parallelepipeds.)

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.
