what is a three - dimensional structure that represents the alternating pattern of particles in a crystal?\no a polyatomic ion\no a crystal lattice\no a covalent bond\no a formula unit
Answer
Brief Explanations:
A crystal lattice is a three - dimensional arrangement of atoms, ions, or molecules in a crystal that shows the repeating pattern of particles. A polyatomic ion is a charged group of atoms. A covalent bond is a chemical bond involving the sharing of electron pairs. A formula unit is the simplest ratio of ions in an ionic compound.
Answer:
B. a crystal lattice
