[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.
Actually it's [Kr]5s1 4d8 Rhodium has an atypical configuration
Zinc's complete electron configuration is 1s22s22p63s23p64s23d10
The outer electron configuration for oxygen is 2s^2 2p^4. This means that oxygen has 6 outer electrons in its valence shell.
Atomic shorthand uses the noble gas before the element in questionAnswer: Cu: [Ar]4s[1]3d[10]Explanation: Copper Cu is an anomaly. Logically we would write 4s[2]3d[9] but for Cu, having the d sub level full is more stable than having the s sub-shell full and the d sub-shell less than full. Chromium also has this anomaly, and is written [Ar]4s[1]3d[5]
Noble gas notation is a way of simplifying electron configurations by using the previous noble gas's electron configuration as a starting point. For calcium, the electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2. Using the noble gas argon (1s2 2s2 2p6 3s2 3p6) as the starting point, the noble gas notation for calcium is [Ar] 4s2.
It is [Ar] 3d1 4s2
Yes it is possible to write the noble gas configuration of all elements, though it is not possible to list all of them here.
Actually it's [Kr]5s1 4d8 Rhodium has an atypical configuration
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
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]
Electron configuration of uranium is: [Rn]5f36d17s2
The electron configuration of fluorine is 1s2 2s2 2p5.
In noble gas notation, you don't have to write the electron configuration up to that noble gas. You simply put the noble gas in brackets [noble gas] and then continue to write the electron configuration from that point. It just makes it shorter and easier to write electron configurations for elements with a lot of electrons.
[Ne] 3s2 3p6
The electron configuration of aluminium is [Ne]3s2.3p1.
Zinc's complete electron configuration is 1s22s22p63s23p64s23d10
Because it is shorter and easier to write. Also saves time when compared to writing the complete electron configuration.
