What principle energy level has no F sublevel?

The second principle energy level (n=2) does not have an F sublevel. The F sublevel belongs to the third principle energy level (n=3) and higher energy levels.


What is the number of electrons energy levels?

What is the difference between d and f orbitals?

The main difference between d and f orbitals is their energy levels and shapes. D orbitals have slightly higher energy levels and are shaped like cloverleafs, while f orbitals have even higher energy levels and more complex shapes, like dumbbells with donut shapes around them. Additionally, d orbitals are found in the third energy level and higher, while f orbitals are found in the fourth energy level and higher.


Which principal energy level has no f sublevel?

The first two principal energy levels (n = 1 and n = 2) have no f sublevel.


Can an element be identified by the electron configuration?

Yes, but an electron configuration could be that of an ion. The identification of an element depends on the number of protons in its nucleus, so only when the species is also neutral can the electron configuration be used to identify it. Examples 1s2 2s2 2p6 is the electron configuration of Neon but also of F-. Take the superscripts and add them together to get the atomic number and if neutral must be Neon but if negative is that of F-


The electron cloud is divided into what?

The electron cloud is divided into s, p, d, and f orbitals. These orbitals also occur at different principle energy levels.

How many energy sublevels are in fourth energy level?

There are four energy sublevels in the fourth energy levels: 4s, 4p, 4d, and 4f.


Why are only certain colors of light absorbed by and emitted from an atom?

Each atom has specific energy levels for their electrons. When light is absorbed or emitted, it causes these electrons to move between energy levels. Only light with energy corresponding to the energy difference between these levels will be absorbed or emitted, resulting in specific colors for each atom.


The measure of a photon's energy is?

The measure of a photon's energy is proportional to its frequency, according to the equation E = h * f, where E is energy, h is Planck's constant, and f is frequency. Photons with higher frequencies have higher energy levels.
