Please explain to me the relationships between electron shells, subshells, and orbitals?

Also, How is the orbital configuration for Hydrogen and Helium different? Aren't both of them 1s?

Please explain to me the relationships between electron shells, subshells, and orbitals?
Electrrons are found in electron clouds, with the shells and sub shells describing where they are most likely to be found. As you look at the periodic table, the periods are labeled 1 through 7. These are the number of shells for the elements in that row. The shells have sub shells. The sub shells have distinct shapes. Electrons also spin either clockwise or counterclockwise and are paired when possible. Sub shells: s,p,d,f,. Lower energy levels are filled first.

H has 1 electron only in the 1st s shell. It will spin .

He has 2 electrons in the 1st s level, spinning in opposite directions. The s shell is round.
