An ion with a charge of -3 is formed when an atom of an element gains three extra electrons. This can happen through chemical reactions where the atom accepts electrons from other atoms that are willing to donate them. One example is nitrogen, which can form the nitride ion (N3-) by gaining three electrons.
Bromine is indeed a diatomic element, but bromideis the ion, so it can be made of just one charged atom.
Naturally-occurring strontium ions typically have a charge of +2. This is because strontium, which is an alkaline earth metal, loses two electrons to achieve a stable electronic configuration, resulting in the Sr²⁺ ion.
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.
Polonium (Po) typically forms a 2+ cation, known as the polonium(II) ion. This ion has a charge of +2 due to the loss of two electrons from a neutral polonium atom.
[Kluged from Wikipedia and others] Hydrogen (H) (Standard atomic mass: 1.00794(7) has three naturally occurring isotopes: Protium 1H, Deuterium 2H, and Tritium 3H. Other, highly unstable nuclei (4H to 7H) have been synthesized in the laboratory but not observed in nature.
Bromine is indeed a diatomic element, but bromideis the ion, so it can be made of just one charged atom.
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
Fluoride is a negatively charged ion of the element fluorine. Fluorine is a naturally occurring element, while fluoride is typically found in compounds like toothpaste and water. So they are not the same thing, but they are related.
Potassium as potassium ion naturally occurs in sea water and in several minerals and ores.
Naturally-occurring strontium ions typically have a charge of +2. This is because strontium, which is an alkaline earth metal, loses two electrons to achieve a stable electronic configuration, resulting in the Sr²⁺ ion.
Ac3+
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.
