Question

Cations and anions combine in a crystal to form which type of a compound?

• A. Ionic
• B. Metallic
• C. Covalent
• D. Dipole-dipole

Answer 1

The correct option is A Ionic

Cation is a positively charged species and anion is a negatively charged species. We know that opposite charges always attract each other and this force of attraction is called the electrostatic force of attraction. It leads to the formation of ionic compounds. An example of an ionic compound is sodium chloride $\left(NaCl\right)$.
