Electrons are basically surrounding the nucleus (containing the protons and the neutrons), and are "swirling" around the nucleus, forming a cloud like shape around the nucleus.
Electrons occupied certain discrete energy levels around the nucleus.
Electron shells, orbitals, and sub-orbitals.
The atom with the greater attraction for shared electrons in the molecule is the more electronegative atom.
the electrons
An ion.If the atom loses electrons it becomes a positive ion, a cation.If the atom gains electrons it becomes a negative ion, an anion.
The negatively charged particles that move around the atom's nucleus is called electrons.
Electrons are generally gathered around an atom beginning with the lowest possible quantum numbers.
Electrons occupied certain discrete energy levels around the nucleus.
Electron shells, orbitals, and sub-orbitals.
Current is the flow of electrons from one atom to the next. Current is measured in amps.
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.
The electrons in an ordinary electrical circuit come from the atoms in the conductive material of the circuit, such as copper wires. When a voltage is applied, the electrons in the material are pushed and flow through the circuit, creating an electric current.
The flow of electrons from atom to atom is an electrical current.
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
