Dear Hankes,
Look at the Course Book! and then read off the answers from there.


I don't know your Level of Study but Think On This:
Try to investigate around the Problem and you will soon begin to understand what the questions mean.

Look at the Periodic Table, especially the table called 'Electron Configuration of Elements', and see if you can work out to which elements this electron might belong (for an un-excited atom).

You will see that n = 4 comes in with Potassium (4s)
Could your L= 3 electron be in this atom?
Have a look further up where 4 f starts with Cerium. Is it possible to have a Ground State m=2?
Here you may find it useful to draw the standard diagram with radius L and put in the various values of m. Here I identified 4 elements (in the Lanthanides) which could contain this electron in the Ground State with m = plus or minus 2 depending on exact energy levels. Remember all elements higher than this should contain it!

This process will give you a feel for the Quantum Numbers in Atoms which will help you a lot later. I haven't puzzled through the full meaning of your Question - so do it yourself.
But remember what I have asked you is for the GroundState and with suitable excitation any lower atom could have the electron in this State!!!!!!


Ask your teacher or another student what they understand and try to help them with any knowledge that you have gained!

Ask this question on the Chemistry Section where they have a much more intimate knowledge of this area than I do.

Answer 2

If i can undergo in strategies maximum magnificent, there are 8 valence electrons interior the outter shell. under is a quote from Wikipidea: The valence shell is the outermost shell of an atom in its uncombined state, which includes the electrons maximum probable to account for the character of any reactions related to the atom and of the bonding interactions it has with different atoms. The outermost shell of an ion isn't many times termed valence shell. Electrons interior the valence shell are suggested as valence electrons. The actual chemist Gilbert Lewis became responsible for many of the early progression of the thought of the participation of valence shell electrons in chemical bonding. Linus Pauling later generalized and prolonged the thought jointly as applying insights from quantum mechanics. In a noble gasoline, an atom has a tendency to have 8 electrons in its outer shell (different than helium, it is merely waiting to fill its shell with 2 electrons). This serves because of fact the kind for the octet rule it is many times desirable to considerable team components of the 2nd and 0.33 sessions. in terms of atomic orbitals, the electrons interior the valence shell are disbursed 2 interior the only s orbital and 2 each and each interior the three p orbitals. For coordination complexes containing transition metals, the valence shell incorporates electrons in those s and p orbitals, as nicely as as much as ten extra electrons, disbursed as 2 into each and each of five d orbitals, to make an entire of 18 electrons in an entire valence shell for this way of compound. this is declared because of fact the eighteen electron rule. each and each shell (n=a million, 2, 3, 4) can carry 2, 8, 18, or 32 electrons (2n2 electrons). that's needed notice that the form of valence electrons isn't inevitably equivalent to the full form of electrons in a given electron shell. as an occasion, because of fact the three-D subshell has an stronger potential than the 4s subshell, the three-D electrons are seen to affix the 4th valence shell. So, jointly as the third electron shell can incorporate an entire of 18 electrons (2 interior the 3s orbital, 6 interior the 3p orbitals, and 10 interior the three-D orbitals), the third valence shell includes in basic terms 8 electrons because of fact the three-D electrons tend to be not area of the third valence shell.
