Fluorine can only form fluoride ions, F- ; it never gives off one or more of its electrons.
Bromine is the only element that matches this description.
When an element forms a negative ion, the name changes to IDE, fir example: chloride
Hydrogen is the element that can form both positive (H+) and negative (H-) ions. When hydrogen gains an electron, it forms a negative ion, and when it loses an electron, it forms a positive ion.
Chlorine (Cl) in the 3rd period can form a -1 ion by gaining an electron to achieve a full outer electron shell (electron configuration of 2,8).
+1
The element hydrogen forms an ion with the same charge as the ammonium ion, which is +1. When hydrogen loses an electron, it becomes a hydrogen ion with a +1 charge, just like the ammonium ion.
Bromine is the only element that matches this description.
The ion is awesom
The third period element that forms a 3- ion is sulfur.
Sodium forms 1 type of ion; namely, Na+.
The common ion charge for the element Lithium (Li) is +1.
Sodium ions have a charge of 1+
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
No element on its own has a charge. However, in all of its compounds sodium forms a positive ion.
When phosphorus forms an ion, it typically gains three electrons to achieve a stable electron configuration. This results in the formation of a phosphide ion with a 3- charge.
Oxygen
When an element forms a negative ion, the name changes to IDE, fir example: chloride
