Answer 1

Answer:

Required Answer:-

(a) A metal which is brittle. Zinc

(b) A non-metal which is a good conductor of electricity. Graphite

(c) The hardest naturally occurring substance. Diamond

(d) The most ductile metal. Gold

(e) A gaseous non-metal. Oxygen

Note:-

Zinc is a metal which can be made ductile and malleable when heated to higher temperatures of 100°C -150°C.

Diamond is a good conductor of only heat not electricity.

Whereas graphite is a good conductor of both heat and electricity..
