How To Find Number Of Atoms Per Unit Cell

Question: Draw the unit cell of HCP. What is the coordination number, atomic radius, and effective number of atoms per unit cell? Also calculate the packing factor.

  • In a unit cell, an atom's coordination number is the number of atoms it is touching. The hexagonal closest packed (hcp) has a coordination number of 12 and contains 6 atoms per unit cell. The face-centered cubic (fcc) has a coordination number of 12 and contains 4 atoms per unit cell.
  • Atoms Per Unit Cell When considering atoms per unit cell, remember some atoms are shared by other cells in the structure in planes above and below as well as the same plane as the unit cell being
  • Determining lattice points per cell in FCC. Ask Question 3. 1 $\begingroup$ I'm having hard times understanding the concept of lattice point and unit cell. For example, let's say we need to determine the number of atoms per unit cell in SC BCC and FCC. For SC, in my understanding each corner is like the center of the atom. So there are 4 quarters of the atom which makes one whole atom. In BCC
  • unit cell The number of atoms per unit cell is the product of the number of atoms per lattice point and the number of lattice points per unit cell. In most metals, one atom is located at each lattice point.
