subshell letters (in order and shape name) - s (sphere), p (dumbbell), d (pedal), f (double pedal)
how to setup orbital order - orbitals in the same column, energy levels in the same row.
shave off the top corner.
Group 1, Group 2, Group 7, Group 8 electron config values - s^1, s^2, p^5, p^6
monovalent, divalent - monovalent: 1 electron needed to gain or lose to fill valence
divalent: 2 electrons needed to gain or lose to fill valence
equilibrium spacing - distance between two atoms where net force is zero.
minimum energy level.
, bonding energy - the amount of energy needed to separate two charged particles at an infinite distance.
ionic bonding properties and reason - melting point : strong bonds
brittle : rigid/fixed atom arrangement
electrically insulated : very stable electrons
metallic bonding and ion core - ion cores is the nucleus and non-valence electrons of an atom.
metals are made of this. the valence electrons are shared amongst themselves.
van der Waals forces - very weak intermolecular forces of attraction
IMFs in inert gasses - only van der waals
anions for hydrogen bonding - fluorine, oxygen, chlorine
metal-ionic bonds - bonds of a substance with considerable ionic and metallic bonds.
occurs when two metals with large electronegativities are together.
as electronegativity difference increases, so does percent ionic bond.
major unit cells - FCC, BCC, HCP, Simple
FCC measurements & characteristics - Reference Measurement: 4r is face diagonal
Edge Length : 2 sqrt(2) x r
Volume : 16 sqrt(2) x r^3
