b) The ion with the largest size: Se +4 or Se +6: c) The element with the largest atomic radii: Cr or Co: d) The element with the largest atomic radii: Li or Ne: e) The one with the largest radius: C or C +4: f) The element with the largest ionization energy: Li or K: g) The element with the largest ionization energy: The corona is known to be very hot because it has ions with many electrons removed from the atoms. At high enough temperatures the atoms collide with each other with such energy to eject electrons. This process is called ionization. At very high temperatures, atoms like iron can have 9 to 13 electrons ejected.
In the example above, sodium has 11 electrons: two electrons in the first energy level (1), eight electrons in the second energy level (2), and one electron in the third energy level. The electron in the 3s 1 orbital is the focus of the example.
