Ch 3 Flashcards
Density as you move down row and to right
Increase
Periodic property
Property predictable based en objects position in table
What is period of period table
18
Main group elements are usually found where
S or P block
What are groups
Columns of elements
Ground state
Lowest -energy level
Degenerate
Systems of equal energy
Paramagnetic
Magnetism because electron counts aren’t full
Order of stability
Full / half / any thing else
Effective nuclear charge
Atomic # - core elections
What trends does atomic radius have
As you move down left it increases
ISO electric series
Atoms with same # electrons
What force do atoms feel when outside nuclei’s
Enc
What force do atoms feel when inside nucleus
Full charge of protons
How to determine metal atomic radius
Half distance between elements next to eachother
How to determine non metal atomic radios
Half distance between two atoms banded together
Atoms without unpaired electrons react how to magnets
Repelled
Ionization energy
Energy required to remove election
Ionization energy trends
Up right because when there is full orbital it is harder to remove electron and when atom is smaller it is harder to removd
Electron affinity
Energy associated with gaining electron
Electron affinity trends
upper right is biggest negative
Metallic trends
Down left
where do you pull electrons from
highest energy level
weird rows for electron configs
copper and chromium
