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.
1: 1+ 2: 2+ 13: 3+ 14: 4+/- 15: 3- 16: 2- 17: 1- 18: Neutral Transition metals (elements between groups 2 and 13) are able to have varied charges that there is no real rule for.
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 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.
Elements are neutral. Two neutral atoms combine to make a neutral compound. Ions have charges. But two ions, each having a charge of +1, would not combine to make an ion having a charge of +2, because they would repel each other. Positively charged ions combine with negatively charged ions to make neutral compounds.
When group 1A elements form ions, they form cations with a +1 charge.
