WebJul 18, 2024 · This is a chart of the most common charges for atoms of the chemical elements. You can use this chart to predict whether or not an atom can bond with another atom. The charge on an atom is related to its valence electrons or oxidation state. An atom of an element is most stable when its outer electron shell is completely filled or half-filled. WebThe size of Cr⁶⁺ ion carries 6 positive charges and is very small because 18 electrons are attracted by 24 nuclear charges. Therefore, the charge density (i.e. charge : volume ratio) of Cr⁶⁺ ion is very high. This leads to a very high polarizing power of Cr⁶⁺ ion, and the electron clouds of the surrounding anions are drawn back to the Cr⁶⁺ ion.
