select all the correct answers. which two properties are characteristic of ionic compounds? brittleness…

Brief Explanations:

Ionic compounds have strong electrostatic forces between ions. This leads to high melting points as much energy is needed to break the lattice. Also, the regular ionic - lattice structure makes them brittle as a shift in ions causes repulsion and breakage. Ductility and malleability are properties of metals. Ionic compounds have high boiling points due to strong inter - ionic forces.

Answer:

brittleness, high melting point
