The group on the Periodic Table that generally has a 2- charge is the chalcogens. This is the group that contains oxygen, sulfur, etc. Despite this, these elements can have different oxidation states.
The group that forms 2+ ions is the alkaline earth metals. These metals lose two electrons in order to have a stable noble gas configuration. Elements in this group are magnesium, calcium, strontium, barium, and radium (which is radioactive).
The elements in group 16 on the periodic table will form -2 ions. These elements have 6 valence electrons, which means they need 2 more to achieve noble gas electron configuration. When they gain these 2 electrons, they will have a -2 charge (remember, electrons are negative.) Group 16 consists of oxygen and sulfur (far and away the 2 most common), as well as selenium, tellurium, and polonium (a lot less common.)
It is an ION e.g. oxide O2- (not stable in water, strong basic) and sulfide S2- (weakly basic in water)
Assuming you mean +2, they are the alkaline earth metals (group 2).
Assuming you mean +2, it is the alkaline earth metals, group 2-A on the periodic table.
These are the elements from the group 2 of the periodic table.
Group 2 has a 2+ charge, and group 6 has a 2- sign.
These are the alkali earth metals Be, Mg, Ca, Sr, Ba, Ra.
They form cations with the charge 2+.
S - Sulfur or any group 16 element
All the elements in groups 14-17 form anions. They all gain an electron. For example out of the these elements: F would be most likely because its the only one that is in a group 17. All the others wouldn't gain one. Because they are in groups 2,13,1,1. All the elements in groups 14-17 form anions. They all gain an electron. For example out of the these elements: F would be most likely because its the only one that is in a group 17. All the others wouldn't gain one. Because they are in groups 2,13,1,1.
Non metals (groups 17, 16, 15)
All the elements in the periodic table of elements are electrically neutral; they do not have charges as elements, although they have the potential to engage in chemical reactions that will turn them into charged ions, in most cases. The different groups tell you what kinds of chemical reactions the elements are capable of, not what kind of charge they have.
Lithium generally has a charge of +1.
Most likely, hydrogen will form a cation, meaning it will have a positive charge of +1

Non metals (groups 17, 16, 15)
Zn will most likely get a 2+ (positive) charge!
groups 11 and 12
All the elements in the periodic table of elements are electrically neutral; they do not have charges as elements, although they have the potential to engage in chemical reactions that will turn them into charged ions, in most cases. The different groups tell you what kinds of chemical reactions the elements are capable of, not what kind of charge they have.
Lithium generally has a charge of +1.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
There are three types of elements: metals, metalloids, and nonmetals. Most elements are metals.

The two most reactive groups of elements in the periodic table are the alkali metals and halogens.
