The arrows represent which way youre meant to go when writing the configuration of an element using ________.
New cards
2
main shells
Subshells are located within the ________; they are essentially different arrangements of electrons in the ________.
New cards
3
D subshells
________ can hold a maximum of 10 electrons.
New cards
4
P subshells
________ can hold a maximum of 6 electrons.
New cards
5
main shell
Represents the number of electrons in each energy level, or ________ of an atom.

While the electron configuration of elements is typically expressed through forms such as the main shell configuration and subshell configuration, there exists another form
shorthand electron configuration
New cards
7
because 2+2+6 = 10
2p^6, the final subshell of Fluorine, can be written as 2p^5 instead
New cards
8
this gets complicated with elements as their electron counts increase
heres an example with Tin (atomic number 50)
New cards
9
SEC makes reference to the previous noble gas
group 8 elements, considering that they all have full outer shells
New cards

We can now effectively remove all the subshell notation that makes up Krypton, and just replace it with something like this
[Kr]
New cards
11
[Kr] 5s^2 4d^10 5p^2
the bolded numbers add to 14, which is the amount of electrons needed beginning from Tin, the nearest noble gas
