How many orbitals can occupy the 5f subshell? There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. Thus, the answer is B. Do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold.
The 2p, 3p, 4p, etc., can each hold six electrons because they each have three orbitals, that can hold two electrons each (3*2=6). The 3d, 4d etc., can each hold ten electrons, because they each have five orbitals, and each orbital can hold two electrons (5*2=10).
Any molecule will always have a vacant molecular orbital (MO). If not vacant then at least partially filled antibonding MO. And there will be many molecules with vacant antibonding MOs. If you want to know whether a molecule has a vacant bonding MO, electron counting and MO diagram would help.

| 4 | s | 32 |
In the Hydrogen atom, 4d orbital has a lower energy than the 5s orbital. This is because when you have only a charged nuclear core and a single electron, the energy of orbitals depends only on the principal quantum number n. 5s orbital is thus filled before 4d orbitals.
Each orbital in a subshell has a characteristic shape, and is named by a letter. They are: s, p, d, and f. Within any particular shell, the energy of the orbitals depends on the angular momentum of orbitals s, p, d, and f in order of lowest to highest energy. No two orbitals have the same energy level.
We say that the 4s orbitals have a lower energy than the 3d, and so the 4s orbitals are filled first. The electrons lost first will come from the highest energy level, furthest from the influence of the nucleus. So the 4s orbital must have a higher energy than the 3d orbitals.
So, it is not held tightly by the nucleus. As a result, the electron has to be in a higher energy level orbital because it farther away from the nucleus. Therefore, electrons in the lower energy s orbital with higher penetration are less shielded by other electrons and experience a higher Zeff than p orbital electrons.
According to the Aufbau principle, the 4s sublevel is filled before the 3d sublevel because the 4s is lower in energy. As the 3d sublevel becomes populated with electrons, the relative energies of the 4s and 3d fluctuate relative to one another and the 4s ends up higher in energy as the 3d sublevel fills.
Even though 5s orbitals have a higher principal quantum number than 4d orbitals, (n = 5 compared to n = 4), they're actually lower in energy. As a result, 5s orbitals are always filled before 4d orbitals. 5s, 5p, and 6s orbitals are all lower than 4f orbitals.
The outermost orbital shell of an atom is called its valence shell, and the electrons in the valence shell are valence electrons. Valence electrons are the highest energy electrons in an atom and are therefore the most reactive.
In this sense the third shell can hold 8 electrons. 4s2 not the third shell, but the next 10 electrons go into the 3d orbitals that are part of the third shell but shown on the fourth shell level. So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.
Originally Answered: why is it that an orbital can contain at most only 2 electrons? This occurs due to Pauli's exclusion principle . It states that two electrons(fermions to be precise) cannot be at the same quantum state at the same time because fermions have anti symmetric wave function.
The names of the electron shells come from a fellow named Charles G. Barkla, a spectroscopist who studied the X-rays that are emitted by atoms when they are hit with high energy electrons. He noticed that atoms appeared to emit two types of X-rays.
Explanation: In an atom, a shell is a collection of subshells with the same principle quantum number, n . Orbitals each hold two electrons, and electrons in an orbital with the same principle quantum number, angular momentum quantum number, and magnetic quantum number, ml are part of the same orbital.
Maximum number of orbitals in an energy level (n2)
| Principal Energy Level (n) | sublevels | electrons |
|---|
| 1 | 1s | 2 |
| 2 | 2s 2p | 2 + 6 |
| 3 | 3s 3p 3d | 2 + 6 +10 |
| 4 | 4s 4p 4d 4f | 2 + 6 + 10 + 14 |
The third shell in its lowest state has room for 8 electrons but including the higher energy 3d electrons it has a capacity of 18 electrons.
Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
The s subshell has 1 orbital that can hold up to 2 electrons, the p subshell has 3 orbitals that can hold up to 6 electrons, the d subshell has 5 orbitals that hold up to 10 electrons, and the f subshell has 7 orbitals with 14 electrons.
Yes, it is very much possible to fill an orbit with 3 electrons, because the maximum number of electrons that can be obtained in an orbit is 8. Yes,we can fill 3 electrons in an orbit. Orbit is basically an earlier concept of electronic configuration around the nucleus of an atom.
The orbital names s, p, d, and f stand for names given to groups of lines originally noted in the spectra of the alkali metals. These line groups are called sharp, principal, diffuse, and fundamental.
The f orbital has 15 protons to complete a fifth level of a tetrahedral structure. The f orbital is more complex, but follows the same rules based on proton alignment as the p and d orbitals. It is based on the points in the nucleus rotation where the gluons of opposite spin protons align.
Subjects. Electron orbitals of excited hydrogen atoms can be observed directly. Orbitals lie outside the nucleus and their properties are described by mathematical wavefunctions. These functions are difficult to study because measuring observable components can destroy other quantum features.
If you look carefully, you will notice that a 1s orbital has very little electron density near the nucleus, but it builds up to a maximum as you get further from the nucleus and then decreases beyond the contour. It is sort of like a hollow tennis ball.
The angular quantum number (l) describes the shape of the orbital. Orbitals have shapes that are best described as spherical (l = 0), polar (l = 1), or cloverleaf (l = 2). They can even take on more complex shapes as the value of the angular quantum number becomes larger.
There are four types of orbitals that you should be familiar with s, p, d and f (sharp, principle, diffuse and fundamental). Within each shell of an atom there are some combinations of orbitals.
