[Kr] 5s(1)
or, in the longer version
1s(2) 2s(2) 2p(6) 3s(2) 3p(6) 4s(2) 3d(10) 4p(6) 5s(1)
Note: All the numbers in the parentheses are supposed to be in superscript (not sure how to do it) and they represent the number of electrons in the sublevel. The first configuration uses the noble gas Krypton (basically an abbreviated form of electron configuration). Both configurations are according to the Aufbau principle (lower energy levels are filled in first). So, if you're confused when you see, for example, 4s before 3d, this is just according to the principle.
The electron configuration of rubidium is: [Kr]5s1.
Actually it's [Kr]5s1 4d8 Rhodium has an atypical configuration
2s22p4
An electron configuration refers to the distribution of electrons in orbitals. Since there are no ions given for this question, an electron configuration cannot be provided.
Zinc's complete electron configuration is 1s22s22p63s23p64s23d10
[Ar] 4s2
It is [Ar] 3d1 4s2
Actually it's [Kr]5s1 4d8 Rhodium has an atypical configuration
Yes it is possible to write the noble gas configuration of all elements, though it is not possible to list all of them here.
The electron configuration of aluminium is [Ne]3s2.3p1.
Cobalt electron configuration is [Ar]3d7.4s2.Nitrogen electron configuration is [He]2s2.2p3.
It is a shorthand form of the electronic configuration. A typical example is Potassium Full electronic configuration 1s2 2s2 2p6 3s2 3p6 4s1 Noble gas notation [Ar] 4s1
Electron configuration of uranium is: [Rn]5f36d17s2
The noble gas (electron) configuration is a scheme for writing the electron configurations of elements in a kind of "shorthand" so it is easier to write them. For potassium element - not ion , [Ar] 4s1 is the way it is written in noble gas configuration. If we could not use this shorthand and had to write out the electron configuration completely, it would like this:1s2 2s2 2p6 3s2 3p6 4s1Wikipedia has other information on potassium, and a link is provided.For Sodium it is [Ne]3s1 and thus for sodium ion it is just [Ne]
2s22p4
An electron configuration refers to the distribution of electrons in orbitals. Since there are no ions given for this question, an electron configuration cannot be provided.
The electron configuration of fluorine is 1s2 2s2 2p5.
The electron configuration 1s22s22p63s23p64s23d5 is for manganese. Not 3d !
