Which element is likely to be the best conductor of electricity?
copper
lithium
iodine
silicon

Option (a) is the correct answer.

Explanation:

Lithium is an alkali metal and it is soft in nature. Therefore, it cannot be drawn into thin wires.

Hence, lithium is not the best conductor of electricity.

Whereas copper due to its ability to be drawn into thin wires and sheets and also it has free electrons it acts a very good conductor of heat and electricity.

Iodine being a non-metal is a poor conductor of electricity and silicon being a metalloid is also not a best conductor of electricity.

Thus, we can conclude that copper element is likely to be the best conductor of electricity.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
