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. WebIn this video we will write the electron configuration for Ca2+, the Calcium ion. We’ll also look at why Calcium forms a 2+ ion and how the electron configur...
