I have attached a photo below of the answer, it is very detailed. If you want a typed up version, here you go.
A sodium atom has 11 protons and 11 electrons. 2 electrons will go in the first shell, 8 will go in the second shell, and 1 will go in the third shell. Because sodium has 11 electrons, it has one extra in the third shell, making it unstable. It will get rid of that single electron and it’s third shell so it can become stable. After this, there will be more protons than electrons, giving it a positive charge. Hope this helps you and again, the photo holds a lot more detail with some notes and a drawing that can help you. Good luck and stay safe!
