Metals have such an electronic configuration which make them able to conduct electricity. In the outer most shell of a metallic atom, there are lone pair(s) of electrons. When a metallic atom is exposed to any form of energy like electricity, they jump from their original shell to the shell of higher energy. In this way lone pairs find vacant spaces for electrons in other atomic shells and jump from one shell to the other. As long as electricity is transferred the electrons keep on moving and this transfer of energy because of the flow of electrons is known as electricity.
Flow of electric current is called electricity. Electricity is produced due to the motion of ions or charges. Metals are good conductors of heat and electricity. The reason is that they have free electrons in their outermost shells. These electrons keep on jumping from one shell to the other, whenever they are exposed to any form of energy. As a result of this electron movement, electricity is produced in the metals.
The outer shell electrons are delocalised. The electrons are free to flow and the electrons carry a current.
Free electrons in metal can help to conduct electricity.
Well I don't really know to be honest... But I guess I should since people say I am good at science but overall I'm not sure...
