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.

Option (c) is the correct answer.

Explanation:

Ionic compounds are the compounds formed by transfer of electrons. An ionic compound contains ions which are arranged in an ordered lattice.

This lattice is repeating in nature and thus results in the formation of a compound.

For example, NaCl is an ionic compound that has an ordered crystal lattice.

Thus, we can conclude that the statement they are made up of particles that are arranged in a repeating pattern, is true.

1. they vary with a higher number because boiling is way hotter than melting
