Question
Which of the following is the correct bond angle in a lattice of silicon atoms?
Solution
The bond angle in a lattice of silicon atoms, which forms a diamond cubic crystal structure, is 109.5 degrees. This is because in a diamond cubic structure, each atom is located at the corners of a tetrahedron, and the angle between any two bonds in a tetrahedron is 109.5 degrees.
