0 an extremely small piece of matter with a negative electrical charge
1 the part of an atom with a negative electrical charge, which moves around the atom's nucleus (= central part)
An electric spark consists of a rush of electrons across the space between the two terminals.
The fixing of the wandering electron to a neutral atom creates a negative ion.
The principal remedy is heat, because it engenders a higher rate of vibration of the electrons.
We have seen that an electric current is really a flow of electrons.
It permits simulation of the coupled dynamics of valence electrons and ionic cores in a molecule or a material.
The 13-cm radius outer wall is permitted to emit electrons where the plasma is in contact.
Where the plasma is in contact with the outer wall, electron space-chargelimited emission is permitted.
