How do you find the number of orbitals?
The number of orbitals in a shell is the square of the principal quantum number: 12 = 1, 22 = 4, 32 = 9. There is one orbital in an s subshell (l = 0), three orbitals in a p subshell (l = 1), and five orbitals in a d subshell (l = 2). The number of orbitals in a subshell is therefore 2(l) + 1.

What does a 2s orbital look like?
The 2 s and 2 p orbitals differ in shape, number, and energy. A 2 s orbital is spherical, and there is only one of them. A 2 p orbital is dumbbell-shaped, and there are three of them oriented on the x, y, and z axes. The 2 p orbitals have higher energy than the 2 s orbital.
How many orbitals are in 4f?

What is noble gas configuration?
Noble gas configuration. Noble gas configuration is the tendency of chemical elements to gain or lose electrons to reach the electronic configuration of a noble gas.
What is the electron configuration of noble gas?
noble-gas electron configuration. An electron structure of an atom or ion in which the outer electron shell contains eight electrons, corresponding to the electron configuration of a noble gas, such as neon or argon.
