Elements in Group 2 of the Periodic Table, such as calcium, magnesium, and strontium, typically have a charge of 2 when forming ionic compounds. This is because they readily lose two electrons to achieve a stable electron configuration.
Elements that will always form ionic compounds with zinc in a 1:2 ratio are those from Group 16 of the periodic table, such as oxygen (O), sulfur (S), and selenium (Se). These elements typically gain two electrons to achieve a stable electron configuration, forming ions with a 2- charge that can combine with the 2+ charge of zinc.
Oxygen usually has a -2 charge as it is a group VI nonmetal. Most of the elements in group VI have -2 charges when they form ions.
The elements in Group 4A are called the carbon group elements. This group includes carbon, silicon, germanium, tin, and lead. They share similar chemical properties such as forming covalent compounds and having multiple oxidation states.
The Group 7A elements, also known as the halogens, typically form ions with a charge of -1. This is because they only need to gain one electron to achieve a stable electron configuration similar to the nearest noble gas.
They can form ionic compounds with halogens.
There's no charge within the atom of each group since there is a same number of electrons (negatively charged) and protons ( positively charged). The charge does not change unless after ionic bonding. The atomic charge changes depending on the reaction.

The most common charge (or valency) is -2. But there are compounds formed by elements of group VIA with valency from -2 to +6
The Group 7A elements, also known as the halogens, typically form ions with a charge of -1. This is because they only need to gain one electron to achieve a stable electron configuration similar to the nearest noble gas.
Group 15 elements are known as the nitrogen group. Some characteristics include having 5 valence electrons, forming covalent compounds with nonmetals, and their compounds often displaying multiple oxidation states. They tend to form compounds that are important in biological processes, such as ammonia and nitrogen gas.
They can form ionic compounds with halogens.
I think what you are asking is about is which group on the periodic table has elements with an oxidation number of -1 in most ionic compounds. That is the 17th group - the halogens.
Yes, group 1 and 2 elements can become cations when they form ionic bonds. Group 1 elements, such as sodium, readily lose one electron to become sodium cations with a +1 charge. Group 2 elements, such as magnesium, lose two electrons to become magnesium cations with a +2 charge in ionic compounds.
Noble gases satisfy the octet rule without forming compounds because they already have a full outer shell of electrons, making them stable and unreactive.
Group 1 elements (such as Sodium and Potassium) readily form compounds because they are highly reactive metals that readily lose their outer electron to form positive ions. Group 7 elements (such as Chlorine and Fluorine) are highly reactive nonmetals that readily gain an electron to form negative ions, making them prone to forming compounds as well.
