Description of Term
When the attraction from the nucleus felt by one electron is lessened or blocked by intermediate electrons.
An uncharged atomic particle of mass 1.67493x10-27 . It resides in the nucleus.
Atoms with the same number of protons (i.e. same atomic number) but a different number of neutrons.
An ion with a net negative charge.
Associated with one particular atom, in which electrons reside
The highest energy shell in an atom, containing valence electrons. All interactions between atoms take place through the electrons of the valence shell.
The cardinal rule of bonding. States that atoms gain stability when they have a full complement of 8 electrons in their valence shells.
German for 'building up', a systematic procedure for determining the electron configuration of any atom
A positively charged particle of mass 1.6726x10-27
Through shielding, the breaking of degenerate orbitals within a shell in multi-electron atoms.
A set of electron orbitals with the same principal and second quantum numbers.
States that no two electrons in an atom or molecule can have the same set of four quantum numbers.
The four numbers that define each particular electron of an atom.
Description of Term
The small, dense central region of an atom around which electrons orbit. Made up of protons and neutrons.
Negatively charged elementary particle of mass
A tenet of quantum mechanics that says that the position and momentum of any particle cannot both be known precisely at the same time.
The energy it takes to remove an electron from an atom.
Any atom or molecule with a net charge.
A set of electron orbitals with the same principal quantum number.
The energy change in an atom when it gains an electron.
ELectrons in the outermost energy shell of an atom.
Description for two elemental species with the same electronic configuration
A rule which says that, when choosing between orbitals, electrons prefer to go in separate orbitals of the same energy.
Orbitals with identical energies
