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.

Explanation: The periodic table contains rows and columns. To find how many valence electrons are in an element, simply locate the column number that it is in, and that determines the number of valence electrons in an element.
WebElements are pure substances with specific properties. Atoms are the smallest units of elements that still retain the element's properties. Atoms contain electrons, neutrons, and protons. Each element is defined by the number of protons in its nucleus. Created by Sal Khan.
