Compare the hardness and brittleness of aluminum versus salt. Suggest a reason, based on the crystal structure of metals versus ionic compounds, why hardness and brittleness are not the same thing.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Answer is (d)a brainliest would be appreciated

The correct answer is:   bri hope this answer was ! : )
