What is the highest sublevel electrons in the element Promethium an f block element occupy?
The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.
Which set of elements has electrons added to the 4f sublevel as the atomic number increases?
The lanthanides, the inner transition metals from 57La through 71Lu.
Which energy sublevel is being filled by the elements Ce to Lu?
4F
What electron configuration of outer sublevels is the most stable?
The electron configuration of the 4f energy sublevel is the most stable is 4f to the 14th power. The electron configuration of outer sublevels that are most stable is 4d up to the 5.5s up to the 1st power.
What is the maximum number of electrons that can occupy the n equals 4 energy level?
there are 16 orbitals in a n=4 shell *since there are 2 electrons in each orbital, that makes 32 electrons total here

Lanthanide and actinide series do not start with lanthanum and actinium explain?
Lets take the Lanthanides as an example. Lanthanum has its 5d sublevel filled before its 4f, even though the 4f is lower in energy and should, by the Aufbau Principle, be filled first. However, this is an exception because it happens to be the most stable configuration. It has one electron in the 5d sublevel and none in the 4f, and since it has no "f" electrons, it cannot be part of the f-bar's upper row (the Lanthanide series). The Lanthanides themselves will each also have one electron in the 5d sublevel, and the first element will also have one in the 4f sublevel. This trend will continue for all 14, and thus the 4f sublevel is filled. Hafnium, the element immediately after the last Lanthanide, will resume filling the 5d sublevel as normal, with two electrons in it and a completely filled 4f sublevel. The anomaly does not really change much; after all, if the valence electron in Lanthanum were not in the 5d sublevel and instead in the 4f, it would start off the Lanthanide series, there would be 14, and it would simply end one element before it normally does. The numbers all add up, in any case, and this is the natural order of things. For Actinides, replace the word Lanthanum with Actinium, Hafnium with Darmstadtium, 5d with 6d, and 4f with 5f. Everything works out perfectly; all the confusion is just caused by the stubborn little electron who doesn't want to be the first f-block element (and so he moves up into 5d, and stays there while the others take their appropiate places, which are moved one up thanks to his desire to maintain stability).
What is the maximum number of electrons that can exist in 4f orbitals?
The maximum number of electrons that can exist in 4f orbitals is 14.-pg. 110 Modern Chemistry table 2:)
What is the maximum number of electrons that can occupy the n equals 4 energy level?
there are 16 orbitals in a n=4 shell *since there are 2 electrons in each orbital, that makes 32 electrons total here
How many electrons can occupy the 4f orbital?
ten. because a d subshell corresponds to an l value of 2, m_l can be -2,-1,0,1,2. so that's 5 orbitals, and 2 electrons can fit into each one (one with a +1/2 spin and one with a -1/2 spin) so that's 10 electrons total.
How many protons and electrons are in the element platinum in each shell?
The electronic configuration by shell for the element Platinum is the same as the filled shells of Xenon (q.v.), plus the following added: 14 electrons in the 4f shell, 9 in the 5d shell, and one in the 6s. Note that protons do not occupy shells in the atom but are bound in the nucleus.
What is the maximum number of electrons each of the following can hold... 2s 5p 4f 3d 4d?
2s: 2 electrons 5p: 6 4f: 14 3d: 10 4d: 10
How many electrons are in 4 f subshell?
Maximum capacity of electrons in f-orbitals is 14, so 4f orbitals may have 1 to 14 electrons.
What in the electrons are being added to the 4f orbitals?
If the valence electrons are being added to the 4f orbitals, that means the element is lanthanides or actinides which further proves that the element is a heavy element and a member of f -block.
