fourth period
The third period is similar to the second, except the 3s and 3p sublevels are being filled. Because the 3d sublevel does not fill until after the 4s sublevel, the fourth period contains 18 elements, due to the 10 additional electrons that can be accommodated by the 3d orbitals.
I was flung towards the atmosphere. Slowly but surely, I made my way inside. On my way there, I began to heat up. I began to vibrate rapidly, and I noted it happened as I entered the atmosphere. I think it was because we sped up so much, but I can't say for sure because I'm an air particle...
