Chem Exam 3
directly
Energy of a photon is ______ proportional to frequency
inversely
Energy of a photon is ______ proportional to wavelength
Zeff
The - increases moving right and up the periodic table.
s
Which of the following types of electrons penetrates most toward the nucleus and therefore has the greatest shielding effect?
state function
best described as a function that depends only on the starting point and ending point of a process.
ionization energy
decreases down a group and increases across a period. (top right)
Pauli Exclusion Principle
each electron can be described with a unique set of four quantum numbers.
Ionization energy
is the amount of energy required to remove an electron from a neutral, gaseous atom.
Aufbau
states that electron's occupy orbitals in order of increasing energy.
Hund's Rule
states that when electrons occupy degenerate orbitals (i.e. same n and l quantum numbers), they must first occupy the empty orbitals before double occupying them.
Halogens
tend to form anions because gaining electrons will fill their octet faster than losing them.
fewer
the smaller ion in a pair will be the one with - electrons.
