Electron Configurations consist of a number denoting the ________________ level. letter denoting the ________________ of orbital. superscript denoting the _____________________ of electrons in those orbitals. The electron configuration of an S atom is: 1s22s22p63s23p4 An orbital diagram can also be used to represent the location of electrons in an atom. In an orbital diagram: Each box represents one__________________. Half‐arrows represent the__________________. The direction of the arrow represents the ______________of the electron. The orbital diagram of helium is 1s The spin of an electron is specified by a fourth quantum number called the _________________. The two possible values of, ms, are _______ (spin up) and _________ (spin down) The three principles that are needed to specify orbital occupancy for the electrons are: Pauli Exclusion Principle: No orbital may have more than ______ electrons, and they must have __________________spins Hund’s rule: Orbitals of the same energy fill _______________ with electrons of the _____________ spins before pairing. Aufbau Principle: energy levels fill from ______________ energy to ______________ energy energy sublevels fill from _____________energy to _____________energy Watch video tutorial on Blackboard Electron Configurations and the Periodic Table (section 8.4) Valence electrons are _____________________________________________________________________. For main group elements, the valence electrons are located in ______________________________. Anions are formed when atoms ___________ enough electrons to have 8 valence electrons Cations are formed when an atom ________________ its valence electrons The periodic table can be divided into blocks representing the filling of particular sublevels (s, p, d or f). Label the colored sections of the following periodic table as “s‐block elements”, “p‐block elements”, “d‐block elements” or “f‐block elements” 2 The number of columns in a block corresponds to the maximum _____________________________________. The row number in the periodic table is equal to the number (or n value) of _____________________________.
