Harry Potter author JK Rowling is creating something magical for her children: an adventure treehouse that looks like Hogwarts:
The Hogwarts-style towers - estimated to cost around £150,000 - are so big that they need planning permission.
Each wooden tree house is to be built on stilts and boasts balconies, carvings and turrets that wouldn’t look out of place in a Potter adventure.
The towers are linked by a rope bridge and can be approached by a secret tunnel hidden underneath a raised wooden walkway.

Only the first one can be found in an hydrogen atom, because it only has one electron. And you need two electrons per orbital.
Each line in the periodic table adds another set of orbitals, in the following order: 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, etc...
All of these plots are for hydrogen alone; only the first one is the ground state. Larger atoms fill up more than one of those orbitals at a time.
