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!
