Name: ______________________________________________ Period:______ Date:____________ Electron Configuration Vocabulary Task Fill in the gaps in the table below Hint/Clue High  Low 2 2 3 1s 2s 2p + X or X - Term Definition/Sample/Example Aufbau Principle The rule that states that electrons fill up the lowest energy shells before those at higher level energies. Atomic number The number of protons and therefore electrons an element has. d-orbital The four-lobed orbital which is found in electron shells 3-4. Electron configuration The arrangement of electrons in an atom Electron orbital diagram Pictorial representation of how electrons occupy the orbitals in each shell of an atom. Energy level Differing distances from the nucleus of an atom which are occupied by electrons. f-orbital The 8-lobed orbital found in the fourth energy level and able to hold 14 electrons Hund’s Rule Electrons fill up all available orbitals individually before pairing up. Atoms which have lost or gained electrons. Ion Name: ______________________________________________ Period:______ Date:____________ Electron Configuration Vocabulary Task 1s 2 Orbital notation  Pauli Exclusion Principle p-orbital [Xe]4s 1 shorthand notation s-orbital Valence electron The electron level, type of orbital and number or electrons found in a given subshell. Electrons can only occupy the same orbital if they have the opposite spin. The 3D dumb-bell shaped orbital which occupies energy levels 2-4. Using the noble gas prior to the element to abbreviate an atoms notation Orbital found in each energy level of the atom Electrons found in the outermost energy level of an atom.
