The orbitals with l 2 are called the d orbitals followed by the f- g- and h- orbitals for l 3 4 5 and there are higher values we will not consider.

Names of f orbitals. Besides the first 2 pictures this question on Quora also gives different names. Other orbitals s p d were named after the words Sharp Principal and Diffuse. It converts a proton to neutron in the next d block to compensate beginning with the 5d block.

These line groups are called sharp principal diffuse and fundamental. It can also be noted that the names of the first four orbitals s p d and f are derived from the descriptions that were initially provided by the spectroscopists who studied the spectroscopic lines of the alkali metals and described them as sharp principal diffuse and fundamental. See The Origin of the s p d f Orbital Labels for additional information.

The seven f-orbitals are due to the secondary angular momentum quantum numbers -3 -2 -1 0 1 2 3. The f-orbitals were named after Fundamental spectroscopic lines as observed in alkali metals. The four different orbital forms s p d and f have different sizes and one orbital will accommodate up to two electrons at most.

The orbitals p d and f have separate sub-levels and will thus accommodate more electrons. There are 15 elements for the f block Z57 to 71 although an odd number affects the number of orbitals 14 2 7. In these elements the last electron usually enters the penultimate ie.

For f orbital Azimuthal quantum number l 3 and the magnetic. The f block elements are also known by the name of inner transition elements. 29 rows f orbital.

In fact Bergmann discovered the series in the sodium spectrum. Different sources seem to be stating different names. These orbitals have different shapes eg.
