Flashcards in 5.1 : Electron Structure Deck (11):
What are shells ?
The energy increases as the shell number increases
What is the shell number / energy level called?
Principal quantum number
What is the electron configuration for krypton?
1s2 2s2 2p3 3s2 3p6 3d10 4s2 4p6 4d10
What is an atomic orbital?
A region around the nucleolus that can hold up to two electrons, with opposite spins
What is the maximum number an orbital can hold ?
What is the shape of a s orbital?
What is the shape of a p orbital?
Can be Px, Py or Pz
What are the number of electrons in each shell?
N= 1 has 2 ( 1s2)
N= 2 has 8 ( 2s2 + 2p6 )
N= 3 has 18 ( 3s2 + 3p6 + 3d10 )
N= 4 has 32 ( 4s2 + 4p6 + 4d10 + 4f14)
How would you draw electron configuration in the electron box model?
Electrons are negatively charged and repel each other
They either spin up or down
The two electrons in an orbital must have opposite spins
The boxes also fill up with one electron each and then double up
How do you write shorthand electron configuration?
You write the noble gas that is just behind it. That counts as the early bit of electron configuration. Manually write the rest until it reaches the required element.
