Answer:
A) Ionic
Step-by-step explanation:
NaBr is an ionic compound. Ionic compounds are composed of ions, which are atoms that have gained or lost electrons, resulting in a net positive or negative charge. In NaBr, the sodium atom donates an electron to the bromine atom, forming a sodium cation (Na+) and a bromide anion (Br-). These ions are held together by the strong electrostatic forces of attraction between the positive and negative charges, resulting in a solid compound with a high melting and boiling point. Ionic compounds are typically crystalline solids that are good conductors of electricity when melted or dissolved in water.
