Question

understanding concepts
2 classifying compare the prop- erties of metals and nonmetals.

Explanation:

Metals are typically shiny, malleable, ductile, good conductors of heat and electricity. Non - metals are often dull, brittle, poor conductors of heat and electricity. Metals tend to lose electrons in chemical reactions (form positive ions), while non - metals can gain electrons (form negative ions) or share electrons.

Answer:

Metals: shiny, malleable, ductile, good heat/electricity conductors, lose electrons in reactions. Non - metals: dull, brittle, poor heat/electricity conductors, can gain or share electrons.
