If you click on the link, you'll see easy instructions on how to do this. I'll follow these steps, so it will be easy to follow along...
#1.# Find the atomic number. I looked it up and it is #7.#
#2.# Determine the charge. This is a neutral element, so there is no need for this step.
#3.# Memorize the basic list of orbitals. It has been written in the link, so I will leave that up for you.
#4.# Understand electron configuration notation. Know when to use which orbital and subscript. All of the exponents add up to the atomic number, unless it is unstable with a charge.
#5.# Memorize (yes, memorize) the order of the orbitals. Which is... (holds breath) #1s^2,2s^2,2p^6,3s^2,3p^6,4s^2,3d^10,4p^6,5s^2,4d^10,5p^6,6s^2,4f^14,5d^10,6p^6,7s^2,5f^14,6d^10,7p^6.# (oganesson)
#6.# Fill in the orbitals according to the number of electrons in the element. Which would be #1s^2,2s^2,2p^3# #color(blue)(2+2+3=7)#
And that's it! The last two steps are basically check your work and use Short hand config. to simplify long configurations (like oganesson)
Hope this helped you!
