The lowest energy shell that contains f orbitals is the shell with n equals?

The lowest energy shell that contains f orbitals is the fourth shell (n=4). Within this shell, the f orbitals are found in the subshell with l=3.

How many types of orbitals are in the sixth shell?

There are four types of orbitals in the sixth shell: s, p, d, and f orbitals. The s orbital is spherical, the p orbitals are dumbbell-shaped, the d orbitals are cloverleaf-shaped, and the f orbitals have more complex shapes. Each type of orbital can hold a specific number of electrons.

How many electrons can be held in the first 4 energy levels?

== Answer== Generally, each sub-shell has its own energy. The sub-shells, listed in order of energy with the number of orbitals in that sub-shell, with the number of electrons each one occupies, are:1s: 1 orbital, 2 electrons2s: 1 orbital, 2 electrons2p: 3 orbitals, 6 electrons3s: 1 orbital, 2 electrons3p: 3 orbitals, 6 electrons4s: 1 orbital, 2 electrons3d: 5 orbitals, 10 electrons4p: 3 orbitals, 6 electronsetc.So, in the first four separate energy levels or sub-shell (1s, 2s, 2p, and 3s) there are 2 + 2+ 6 + 2 = 12 electrons. Note that in these first four sub-shells there are 6 orbitals (with 2 electrons each).

What are the different atomic orbitals?

You can break down the shell and orbitals of an atom on several levels of detail.First, there are the main shells of the atom, and these are numbered 1, 2, 3, 4, etc. (or like some doing it alphabetically K, L, M, N, ...).In the periodic table you will encounter them as seven periods.Each shell holds orbitals (sometimes called sub-shells, but they are not), and different shells have different numbers of orbitals associated with it. The higher the number of the main shell, the more orbitals it contains. In fact, the number of the main shell is equal to the number of orbitals it contains. The types of orbitals are labeled like this: s, p, d, f, and not so very important: g, h, i, etc (alphabetically after i).So far we have:Main shell #1-- contains one orbital (s-orbital)Main shell #2-- contains two orbitals (s-orbital, and p-orbital)Main shell #3-- contains three orbitals (s-orbital, p-orbital, and d-orbital)Main shell #4-- contains four orbitals (s-orbital, p-orbital, d-orbital, and f-orbital)etc...Now we can further break down orbitals! The p-orbital is actually composed of three sub-orbitals and the d-orbital is composed of 5 sub-orbitals and f-orbital in 7 sub-orbitals.So we have:s-orbital: just a single orbital, called just the s-orbitalp-orbitals: composed of 3 sub-orbitals, called the px-, py-, and pz-orbitalsd-orbitals: composed of 5 sub-orbitals, called the dxy-, dxz-, dyz-, dx2-y2, and dz2-orbtialsf-orbitals: composed of 7 sub-orbitals, called fz3, fxz2, fyz2, fxyz, fz(x2-y2), fx(x2-3y2), fy(3x2-y2).etc...And at last, but not least: each sub-orbital has a maximum of TWO electrons in it, only differing in electron spin number.So the maxima per orbital are:s-orbital: just a single orbital, max. 2 electronsp-orbitals: composed of 3 sub-orbitals, max. 6 electronsd-orbitals: composed of 5 sub-orbitals, max. 10 electrons (= number of transitional elements)f-orbitals: composed of 7 sub-orbitals, max. 14 electrons (= number of lanthanides, actinides)(Thanks to JEK, who's original answer I completed with the last paragraph and some minor add's in the first ones)


How many subsheels are there i the n4 principal shell?

The n=4 principal shell contains four subshells, which are designated as 4s, 4p, 4d, and 4f. Each subshell corresponds to a different type of orbital: the s subshell has 1 orbital, the p subshell has 3 orbitals, the d subshell has 5 orbitals, and the f subshell has 7 orbitals. Therefore, the total number of subshells in the n=4 principal shell is four.


How many outer electrons germanium has?

It is got 4 electrons in its outermost shell. The last two electrons fall in the 4p orbitals.


Are electrons located only in specific shells around the nucleus of the atom?

Electrons are located in all the shells before the last shell but when doing equations and working things out, you only refer to the last shell. This is because the shells before the last shell are all full (the first one has only 2 electrons but the rest have 8) and only the outer shell electrons, known as valance electrons, react with other substances.
