nonmetals are often malleable.

nonmetals are often shiny and hard.

nonmetals are often ductile.

For the question, the correct answer is "Nonmetals do not conduct electricity." This is a characteristic of nonmetals. Non-metals do not reflect light. Therefore, they are poor conductors of heat and electricity. Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help. 

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
