Here [Ne] refers to the core electrons which are the same as for the element neon (Ne), the last noble gas before phosphorus in the periodic table. The valence electrons (here 3s 2 3p 3) are written explicitly for all atoms. Electron configurations of elements beyond hassium (element 108) have never been measured; predictions are used below.
Scandium: 21 4s 2 3d 1 Yttrium: 39 ... Noble gas configuration is the electron configuration of noble gases. The basis of all chemical reactions is the tendency of ...
To do this, the nearest noble gas that precedes the element in question is written first, and then the electron configuration is continued from that point forward. For example, the electron notation of phosphorus is 1s 2 2s 2 2p 6 3s 2 3p 3 , while the noble gas notation is [Ne] 3s 2 3p 3 .
Scandium is only the 50th most common element on Earth (35th most abundant element in the crust), but it is the 23rd most common element in the Sun [17] and the 26th most abundant element in the stars. [18] However, scandium is distributed sparsely and occurs in trace amounts in many minerals. [19]
Their electronic configurations include completely filled d ... and La have three valence electrons above a noble gas electron core. ... Scandium, Sc 3d 1 4s 2: 4256 ...
Configurations of elements 109 and above are not available. Predictions from reliable sources have been used for these elements. Grayed out electron numbers indicate subshells filled to their maximum. Bracketed noble gas symbols on the left represent inner configurations that are the same in each period. Written out, these are: He, 2, helium : 1s 2
