Electrons occupied certain discrete energy levels around the nucleus.
The flow of electrons from atom to atom is an electrical current.
Electrons can move from atom to atom and from object to object
If there are excess electrons in an atom, the atom is likely to be ionized; that is, the stom will emit the electrons.
The electron. The electron is has a negative charge. The more electrons that are in a valence shell of the atom the more negative the atom will be.
The neutral atom is Carbon, but other ions can have only 6 electrons.
Electrons are generally gathered around an atom beginning with the lowest possible quantum numbers.
Electron shells, orbitals, and sub-orbitals.
A small core of nucleons (protons and neutrons) surrounded by an attenuated cloud of electrons.
The electrons farthest away from the nucleus are the valence electrons of an atom.
Electrons are located in the electron cloud - the outermost portion of the atom. The electron cloud accounts for about 99% of the space taken up by the atom, yet less than 1% of the mass. A good way of thinking about this is in terms of a football field. Imagine the nucleus of the atom was the size of a blueberry. Place the blueberry in the middle of a football field, and that is the size of the electron cloud in comparison to the nucleus. As you see, the atom is mostly empty space with electrons floating around within. Within the electron cloud, electrons are organized into levels, sublevels, orbitals, and spins. Outermost electrons bond with other atoms. The placement of electrons within an electron cloud determines the stability and chemical properties of an element.

valence electrons
The outer electrons of an atom are called valence electrons.
A single atom of Carbon has 6 electrons, with 4 in the outer shell which it will use to react
All the electrons in an atom form the so-called cloud of electrons.
valence electrons are the electrons located in the outer shell of an atom which are available for reaction
Valence electrons are those in the outermost shell of the atom.
