Electron Configuration Of Potassium In Ground State. (check all possible answers) a. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol.
1s 2 2s 2 2p 6 3s 2 3p 3. [ne] 3s 2 3p 5. So for scandium the 1 st and 2 nd electron must be in 1s orbital, the 3 rd and 4 th in the 2s, the 5 th through 10 th in the 2p orbitals, etc.
Electron configuration is the arrangement of the electrons of a molecule or an atom in the orbitals.
In this way, what is the electron configuration for potassium cation k +? When the atom is in excited state, one or more electrons go to a higher energy state, so electron configuration of the excited atom is different. There are eighteen common exceptions to electron configurations for atoms in the lowest energy state, also called the ground state. Choice (b) is the best answer here.
