The Alkaline metals (Group 1 metals).
This is because they all have one valence electron and to become more stable by completing their outer shells, it is easier to lose 1 electron than it is to gain 7.
Group that tend to form -1 ions include group VIIA
positive charge.

The Group 2 elements, or the Alkali Earth metals, tend to form +2 charges when they become ions. This is because Group 2 metals have 2 valence electrons and it is easier to lose 2 electrons than it is to gain 6 electrons to form a full outer shell.
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 one, not including element 1 (helium) tend to form ions.
positive charge.
Elements in Group 2 of the periodic table form ions with a charge of 2. This group includes elements such as calcium, magnesium, and barium. When these elements lose two electrons, they form ions with a +2 charge.

lose 2 electrons and form ions with a 2+ charge.
The Group 2 elements, or the Alkali Earth metals, tend to form +2 charges when they become ions. This is because Group 2 metals have 2 valence electrons and it is easier to lose 2 electrons than it is to gain 6 electrons to form a full outer shell.
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.
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
Elements in Group 13 of the periodic table, also known as the Boron group, can form cations with a 3+ charge. This is because they can lose three electrons to achieve a stable electronic configuration. Key elements in this group include Boron, Aluminum, Gallium, and Indium.
When group 1A elements form ions, they form cations with a +1 charge.
An element should release two of its outermost electrons to obtain +2 ion. The elements in group 2A are the most likely elements to have this configuration. These are known as Alkali Earth Metals.The elements in the 2nd group have 2 valence electrons. Elements give away their valence electrons to get stable electron configuration. The elements in the 2nd group such as beryllium, magnesium, calcium, strontium, barium likely to have positive ion with charge of 2.Group II elements (the alkaline earth metals). This is because this particular group of elements have two extra electrons in their electronic configurations. They need to lose these two electrons to attain the stable noble gas configuration. So they will have a tendency to lose them to other atoms or group of atoms, in the process incurring a double positive charge (since there will now be two less electrons than protons). So Be, Mg and Ca will all form positive ions (cations) with a charge of +2. They are represented by Be2+, Mg2+ and Ca2+ respectively. But, other elements like copper and barium will also form cations of charge +2.
