- 9.6: Electron Configurations of Ions
Write the electron configurations of a phosphorus atom and its negative ion. Give the charge on the anion. Answer. P: [Ne]3s 2 3p 3. P 3–: [Ne]3s 2 3p 6
The electron configurations of ions are obtained by adding or removing an electron to a valence shell orbital of the atom.
When writing an electron configuration, first write the energy level (the period), then the subshell to be filled and the superscript, which is the number of electrons in that subshell. The total number of electrons is the atomic number, Z.
Electron Configurations of Ions. Atoms form ions when they gain or lose electrons. Electronic structures of Cations. A cation (positively charged ion) forms when one or more electrons are removed from a parent atom. When forming a cation, an atom of a main group element tends to lose all of its valence electrons.
Write the electronic structure for the neutral atom, and then add (for a negative ion) or subtract electrons (for a positive ion). To write the electronic structure for Cl -: To write the electronic structure for O2-: To write the electronic structure for Na+: To write the electronic structure for Ca2+: The electronic structure of d-block ions.
