Ionic compounds at room temperature usually exist as solids with distinct crystalline lattice structures.

True

I think true

You are correct. Ionic compounds at room temperature usually exist as solids with distinct crystalline lattice structures. This is because ionic compounds are made up of positively and negatively charged ions, which are strongly attracted to each other. As a result, they form a three-dimensional arrangement called a crystal lattice. The strong forces between the ions hold the lattice together, making the compound solid at room temperature. So, the statement is true.
