The element hafnium has [Xe] 4f14 5d2 6s2 for its noble gas electron configuration. For more information, use the link below.
Use the noble gas notation to write the electron configuration for
The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point onwards. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.
it all depends on the electron configuration if it is positive or negative, you have to look at the transition metals and valence electrons and determine the charge and use the formula n-11s^2 2s^2 2p^6 3s^2 3p^6 3d^10
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]

Aluminum is the 3rd row of our periodic table, so to make its short-hand electron configuration, we start with the noble gas on the end of the previous row, neon (Ne), in this case. Being in the 3A column, Al has 3 electrons in the outer shell, so the configuration is: [Ne] 3s2 3p1

This is best explained by an example: The electron configuration of Strontium (Sr) is: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 This can be simplified by using the noble gas that covers the most items. In this case it is Krypton (Kr) which has an electron configuration of: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 Do you see the similarity in the two configurations? This means that you can use [Kr] to represent 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 So the short-handed (simplified) way of writing Strontium is: [Kr] 5s^2 Everything before the 5s^2 was replaced with [Kr] Note: The "^" symbol means the the following number is in the form of a superscript.
The most common term for a completed outer shell of electrons is that is or has "full" valence electrons.

See the Web Links to the left for a pdf file with a periodic table which shows the electronic configuration (in shorthand notation) for each element. You can also use the WebElements link and select each element to view its electronic configuration.Shorthand notation marks the electron configuration starting with the noble gas element in the previous row. To write out the complete configuration, just write down the configuration for that noble gas in place of the name of the noble gas (you may have to do this several times if you are writing the configuration of an element towards the bottom of the periodic table -- just keep working backwards until you get to the first 1s orbital.For example:The shorthand configuration for iodine (I) is listed as: [Kr]5s24d105p5.First, we must add on the configuration for krypton (Kr) in front:[Ar]4s23d104p65s24d105p5.But since Kr is given in terms of argon (Ar), we must keep going:[Ne]3s23p64s23d104p65s24d105p5.And again for neon (Ne):1s22s22p63s23p64s23d104p65s24d105p5Now we've got everything, so the complete electron configuration for iodine (I) is: 1s22s22p63s23p64s23d104p65s24d105p5Follow the aufbau chart for order of filling - 1s, 2s, 3p, 4s, 3d, 4p, 5s, 4d, 5p and so on.

Sorry, no- it is the proper name (therefore, capitalized) of a radioactive noble gas.
