Web18 jul. 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 neutral atoms are colored gray, cations red, and anions blue. Ions may be larger or smaller than the neutral atom, depending on the ion's electric charge. When an atom loses an electron to form a cation, the other electrons are more attracted to the nucleus, and the radius of the ion gets smaller.
