One formula unit of silver sulfate, Ag2SO4 has 7 atoms.
In a face-centered cubic (FCC) unit cell, there are 4 calcium (Ca) atoms located at the corners of the cell, each contributing 1/8 of its volume. There is also another Ca atom located at the center of the cell, contributing the entire volume. Therefore, there is a total of 4 + 1 = 5 calcium atoms in one FCC unit cell.
To calculate the number of atoms in a unit cell, you first determine the type of unit cell (simple cubic, body-centered cubic, or face-centered cubic) and the number of atoms contributed by each lattice point. Then, you multiply the number of lattice points within the unit cell by the number of atoms contributed per lattice point. For example, a simple cubic unit cell has one atom per lattice point, so the total number of atoms in a simple cubic unit cell would be 1 x 1 = 1 atom.
The repeating group of atoms in a crystal is called a unit cell. This unit cell is the smallest repeating structure that can be used to build up the entire crystal lattice.
The number of formula units in a unit cell depends on the type of unit cell and the arrangement of atoms within the cell. For simple cubic, there is 1 formula unit; for body-centered cubic, there are 2 formula units; and for face-centered cubic, there are 4 formula units.
There are a total of 4 silver (Ag) atoms present in each face-centered cubic unit cell.
There are four zinc blende atoms per unit cell.
One formula unit of silver sulfate, Ag2SO4 has 7 atoms.
There are 8 diamond cubic atoms present in a single unit cell.
The formula unit is Ag2SO4, which contains two silver atoms, one sulfur atom, and four oxygen atoms for a total of seven atoms.
There are a total of 17 atoms in one molecule of silver chromate (Ag2CrO4). This includes 2 silver atoms, 1 chromium atom, 4 oxygen atoms, totaling 7 atoms for each repeating unit in the compound.
The rutile unit cell has a tetragonal structure with titanium atoms at the corners and center of the cell, and oxygen atoms at the faces of the cell.
In a diamond unit cell, each carbon atom is located at the corners of the unit cell. Since there are eight corners in a unit cell, each shared by 8 adjacent unit cells, the contribution to the total number of carbon atoms is 1/8 of a carbon atom per unit cell. Therefore, there is 1 carbon atom per unit cell.
A formula unit of AgCl contains 2 atoms: 1 of silver and 1 of chlorine.
A cubic unit cell contains 8 corner atoms, where each corner atom contributes 1/8 of its volume to the unit cell. Since each silicon atom forms covalent bonds with its neighboring atoms, only 1/8 of each corner atom lies within the unit cell. Therefore, there is a total of 8 x 1/8 = 1 silicon atom in a cubic unit cell.
In a face-centered cubic (FCC) unit cell, there are 4 calcium (Ca) atoms located at the corners of the cell, each contributing 1/8 of its volume. There is also another Ca atom located at the center of the cell, contributing the entire volume. Therefore, there is a total of 4 + 1 = 5 calcium atoms in one FCC unit cell.

For example, a simple cubic unit cell has one atom per lattice point, so the total number of atoms in a simple cubic unit cell would be 1 x 1 = 1 atom.
