Ac3+
Actinium form the ion Ac(3+) and only in AcH2 is divalent.
Fluoride ion (F-) is not an element, but an ion formed from the element fluorine (F). Fluorine is a chemical element on the periodic table, while fluoride ion is a negatively charged particle resulting from the gain of an electron by a fluorine atom.
which element can only formed one ion
ion
The charge of an ion formed by an element on the periodic table is determined by the number of electrons gained or lost by the element. This charge can be positive or negative, depending on whether the element loses or gains electrons.
Lead IV is the 4+ ion formed by the element lead (Pb). Because Pb4+ is a positive ion it must be accompanied by a negative ion.
AI is not an element or compound and so cannot form an ion.
ion attraction
Actinium typically forms ionic bonds due to its tendency to lose its 6s electrons and form the Ac3+ ion. This ion then interacts with other ions or molecules to achieve a stable electronic configuration.
A positive ion ( the one that gives the electron) and a negative ion ( the one that accepts).
No, iodide is an ion formed by the nonmetal iodine.
Sulfur is an element. Sulfide, the ion formed by sulfur cannot exist on its own as a substance because it carries a negative charge and must be accompanied by a positive ion.
