Web20 de jul. de 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. WebThe first thing you need to do is determine the number of the groups that are on each atom. By groups, we mean either atoms or lone pairs of electrons. This is also known as the Steric Number (SN).
