Attention to detail and a good memory. In addition to that, ability to maintain a sense of:balance on a train, ortiming in a music hall.
Yes, because they are metals insulators are nonmetals.
The electrons in electrical conductors also absorb and carry heat, thus are good thermal conductors also.
This is usually true for metals. It is not usually true for nonmetallic substances, however. Diamonds conduct heat much better than copper, but are electrical insulators.
This is because valence shell of metals contains free electros which enables them to conduct heat and electricity.
