Thanks a lot mam 😃 for coming up with this informative session !!
other exceptions of metal and non metals are :-
●Zin , arsenic and mercury are non- malleable metals .
●mercury does not produce ringing sound unlike other metals .
●Graphite is a non metal but it's a good conductor of heat and electricity.

2) lead and mercury(metal) is poor conductor of heat

[@drithibeera1253]

Thank you for the session mam
The answer is Ductility and Malleability...

[@Learning-made-fun1920]

Thank you mam for this Session 🙏🙏😃
The Two Exceptions are,
Based on Conduction oF Heat
1.Metals are generally Good Conductor of Heat but there is Exception that is Lead(Pb)which is a Metal but Poor Conductor of Heat
2.Non-Metals are generally Poor conductor of heat but there is a Non -metal which is Good conductor of Heat that is
Graphite (an allotrope of Carbon)
Based on Sonority
1.All metals are sonorous in nature except Sodium, potassium, lead and mercury.
2.All non-metals are non-sonorous in nature except Graphite (May be Not sure).
Mam If you are reading this Please reply Whether Graphite is Sonorous in Nature or Not
