WebThe electrons which are not attached to the nucleus of a atom and free to move when external energy is applied are called free electrons. Electric field is a region around the charged particle within which the other charged particle will experience a repulsive or attractive force. Valence electrons are loosely attached to the nucleus of a atom. WebFIGURE 1–14 Both electrons and holes tend to seek their lowest energy positions. Electrons tend to fall in the energy band diagram.

When electricity flows, the electrons are considered "free" only because there are more electrons than there should be, and because the transition metals, such as iron, copper, lead, zinc, aluminum, gold etc. are willing to transiently accept and give up electrons from the d -orbitals of their valence shell.

When electrons move through a conducting wire, they do not move at a constant velocity, that is, the electrons do not move in a straight line at a constant speed. Rather, they interact with and collide with atoms and other free electrons in the conductor. WebThe free electrons in a circuit come from the outermost shell of atoms present in the conducting material. The conducting wire is made up of atoms surrounded by electrons. The electrons cannot be created nor be destroyed. The electrons present at the outermost levels of the atom are loosely bond which allows them to move freely. The metal atoms …
