Answer

Answer:

hardness and brittleness

Brief Explanations:

Ionic compounds like chalk are hard and brittle. This allows chalk to leave marks on a chalk - board as it breaks off in small pieces during writing. High melting point is not relevant for writing. Chalk can partially dissolve in water and it's not multicolored by nature of being an ionic compound.
