(20 cards)
Energy and wavelength of electromagnetic radiation are inversely or directly proportional?
inversely
paramagnetic
at least 1 unpaired electron
Diam
has only paired electrons
pattern of ionization energy on the periodic table
energy decreases down the columns and increases across the rows
what kind of electron transition causes energy to be absorbed
when the electron is being excited to a higher energy state
- electron moves to a higher n value
what kind of electron transition causes energy to be emitted
electron moves to a lower n value
what does h symbolize?
planks constant
Rydberg constant
2.178×10^-18
quantum number l equals…
l = 0, …, n-1.
How to find Magnetic quantum number (ml)
-l, …, 0, …, +l
what are possible spin quantum numbers? (ms)
ms = +½ or -½
Aufbau Principle
electrons will occupy the lowest energy level orbital that will receive it
Pauli’s exclusion principle
only 2 electrons per orbital and they must spin in opposite directions
Hund’s rule
each orbital of equal energy must have one electron before a second electron is added
Atomic radius trend on the periodic table
atomic radius decreases from left to right and increases down the columns
ionization energy trend on the periodic table
increases from left to right and decreases down the columns
metallic character trends on the periodic table
decreases across the table and increase down the columns
electron affinity trends
increase across the table and decreases down the columns
what is electron affinity?
the neutral atom’s likelihood of gaining an electron
trend for ionic radius on periodic table
increases down the table and from right to left
