Question Answer
What is interesting about isotopes?They have the Same # of protons, but DIFF number of neutrons
What happens when are closer to the a nucleus than other rings?The closer you are to bed, the lower your energy. The closer an atomic orbital is to the nucleus, the lower the energy, more stability.
What is the purpose of Hund’s Rule? To minimize electron repulsion ⇒ an electron will pair with another electron e.g. 2 or more with the same energy. Lonely Lund Hund.
What is the ground state electronic configuration?Describes orbitals occupied by electrons when they are all in the lowest energy. Aufbaud and Pauli.
What is a Hydride?An ion, when an H+ grabs an electron
What is the Continuum of Bond Polarity?Ionic, Polar Covalent, Non-Polar Covalent.
What is the criteria for a dipole moment?IF the molecule has 1 covalent bond + polarity THEN molecule has a dipole moment.
IF a Sigma bond?THEN sp3
IF a Pi bond?THEN sp2. (Two people entered Pie eating contest)
IF a Triple bond?THEN sp


Question Answer
What are the bond angles in H3O?More than 104.5, less than 109.5
How are bond angles and LPs connected?Inverse Rel of Bond Angles and # of Lone Pairs
How do electrons flow?From high density to low density like water
What is a Hydrogen Halide?HX always has 1 bond w/ 3 LPs all positioned to minimize electron repulsion
Why is there ++ electron density in the region of s overlap?Because as you go down the PT, the shells are getting further and further away from the nucleus and they hold on less tightly!
IF H+ Overlap goes UPTHEN Halogen size goes down
What is connection between length and strength?Inverse relationship
What is the hybridization of carbocations and radicals?sp2 because they are half filled
ionization energy?: the amount of energy required to remove an electron from an atom
Question Answer
electronegativitya measure of the ability of an atom to attract electrons toward itself
electron affinitythe energy change when an electron is added to the neutral species to form a negative ion.
atomic radiusa measure of the typical distance of the atom from the nucleus to the boundary of the electron cloud
ionic radiusa measure of the distance across an atom’s ion in a crystal lattice.
ionization energy?: the amount of energy required to remove an electron from an atom
