Question

which statement is true about ionic compounds? they are made up of many large molecules that are bonded together. they are made up of atoms of only one type of element. they are made up of particles that are arranged in a repeating pattern. they are made up of a random ratio of elements that are bonded together.

Explanation:

Ionic compounds are composed of ions (charged particles) that form a crystal - lattice structure, which is a repeating pattern. They are made up of atoms of different elements (a metal and a non - metal usually), not just one type of element, and not large molecules. The ratio of elements in an ionic compound is determined by the charges of the ions and is not random.

Answer:

They are made up of particles that are arranged in a repeating pattern.
