Explain why thermal and electrical conductivity is so high with copper

Copper is formed of copper atoms, which are closely clustered together. If observed closely, one could witness the movement of electrons between the atoms of the copper. Each copper atom turns into a positive ion by losing one electron. Thus, copper is a lattice of positive copper ions with the movement of free electrons among them.  

Due to movement of electrons freely through the metal, they are also known as conduction electrons. The presence of these conduction electrons makes the copper a good conductor of electricity and heat.  

i think so it’s will be b yes i believe its

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
