WebElectrons carry the basic unit of charge e, equal to 1.6022 × 10 −19 coulomb. They have a small mass and move rapidly. Most electrons in solids are bound to the atoms in local orbits, but a small fraction of the electrons are available to move easily through the entire crystal. These so-called conduction electrons carry the electrical current. Web“Crystal form” is a concept similar to “crystal habit”.
