The elements in Group 1A all form ion with one positive charge. This group is collectively knows as the Alkali metals. They are Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium. Hydrogen ions also can have a positive one charge, but it may, as easily, have a negative one charge.
every element
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.
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
The element with 2 electrons and a charge of -1 is helium. It typically has a charge of 0, but can gain an extra electron to have a -1 charge.
Chlorine typically has a charge of -1 when it forms an ion.
Zinc forms ions with +2 charge (Zn2+).
An ion is an atom of any element that either has a positive or negative charge.

If an element is missing one electron, which is defined as having a negative charge, then the element is a positively charged ion. If an element gains an extra electron, it will have a negative charge and be a negative ion. An element with an equal number of positively charged protons and negatively charged electrons is considered to be a neutral element (in other words, no charge). By the way, no charge for this answer!
No element on its own has a charge. However, in all of its compounds sodium forms a positive ion.
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
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.
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.
The element with 2 electrons and a charge of -1 is helium. It typically has a charge of 0, but can gain an extra electron to have a -1 charge.
If it's an ion with a negative charge, it is an anion.
