1.2 Chemistry - Shorthand Electron Configuration

subshell notation

The arrows represent which way youre meant to go when writing the configuration of an element using ________.

main shells

Subshells are located within the ________; they are essentially different arrangements of electrons in the ________.

D subshells

________ can hold a maximum of 10 electrons.

P subshells

________ can hold a maximum of 6 electrons.

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

because 2+2+6 = 10

2p^6, the final subshell of Fluorine, can be written as 2p^5 instead

this gets complicated with elements as their electron counts increase

heres an example with Tin (atomic number 50)

SEC makes reference to the previous noble gas

group 8 elements, considering that they all have full outer shells

We can now effectively remove all the subshell notation that makes up Krypton, and just replace it with something like this

[Kr]

[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
