WebMay 7, 2024 · For cations you need to be careful and the electron comes from the highest principle quantum shell. So calcium and Titanium (II) have the same number of electrons, but they have different electron configurations (they are not isoelectronic). Calcium (20 electrons): (7.2.8) C a: [ A r] 4 s 2 Titanium (II) (20 electrons): WebJul 20, 2024 · Cations A neutral sodium atom is likely to achieve an octet in its outermost shell by losing its one valence electron. Na → Na + + e − The cation produced in this way, Na +, is called the sodium ion to distinguish it from the element. The outermost shell of the sodium ion is the second electron shell, which has eight electrons in it.
