What does a sequence diagram show?
|
the summary of the order in which orbitals fill in polyelectronic atoms.
|
|
|
Where does the first "overlap" in electron filling occur? Why does this occur?
|
Electrons fill into 4s first instead of 3d because 3d is higher in energy than 4s.
|
|
|
How is the shorthand notation written?
|
Square brackets are written around the nearest noble gas with a lower energy level. The configuration is written from that point up to the element in question.
ex. Ti = [Ar] 4s2 3d2 |
|
|
What connection does the group number in the periodic table have with the number of valence electrons?
|
Every element in a given group has the same number of valence electrons.
