Question 17

why are electrical cables made of copper

Answer 17

very good electrical conductor
inexpensive

Question 18

why are cooking pots made of metal

Answer 18

good thermal conductors
handles- non metal

Question 19

metalloids

Answer 19

elements that lie along non metal division on periodic table
semi-metals
behave like non metals in most ways
conduct electricity better at higher temperatures
