[amp_mcq option1=”Crystal” option2=”Covalent bond” option3=”Semiconductor” option4=”Valence orbit E. None of the above” correct=”option1″]
The correct answer is: A. Crystal
A crystal is a solid material whose atoms, molecules, or ions are arranged in a highly ordered repeating pattern. This ordered arrangement produces a crystal structure that is characteristic of the material.
Silicon atoms combine into an orderly pattern called a crystal. This crystal structure is what gives silicon its unique properties, such as its ability to conduct electricity.
The other options are incorrect because:
- A covalent bond is a chemical bond that involves the sharing of electrons between atoms.
- A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator.
- A valence orbit is an electron shell that is the outermost shell of an atom.
- None of the above is a type of orderly pattern that silicon atoms combine into.
