Group 1 elements a.k.a. Alkali metals lose 1 electron to form 1+ ions
Group 2A elements (alkaline earth metals) tend to lose two electrons to form 2+ ions. This is because they have two valence electrons and tend to achieve a stable electron configuration similar to noble gases by losing those two electrons.
When Group 2A elements form ions they lose the electrons in their outer shell. In doing so they form positive ions known as cations.
Some elements become ions by gaining or losing electrons to achieve a stable electron configuration. When an element gains electrons, it becomes a negative ion (anion), while losing electrons results in a positive ion (cation). This process allows the element to achieve a full outer electron shell and become more stable.
Alkali metals group tends to form ions.They give single electron to gain positive charge.For example : Sodium give one electron to become Na+ ion.
When metallic elements become ions, they lose electrons to form positively charged ions. This process occurs when metals react with nonmetals to transfer electrons, resulting in the formation of ionic compounds. The number of electrons lost by the metal is equal to its oxidation state, which corresponds to the charge of the ion formed.
Nonmetals tend to attract electrons to become negative ions.
lose 2 electrons and form ions with a 2+ charge.
Group 2A elements typically lose 2 electrons when forming ions.

When Group 2A elements form ions they lose the electrons in their outer shell. In doing so they form positive ions known as cations.
Elements become electropositive or electronegative based on their tendency to lose or gain electrons. Electropositive elements have a low electronegativity and readily lose electrons to form positive ions. Electronegative elements have a high electronegativity and tend to gain electrons to form negative ions.

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-.

Lose 2Alkaline-earth metals have 2 outer shell electrons. All atoms "want" eight. They will achieve a full outer shell by losing or gaining the least number of electrons. Since group 2A elements have two valence electrons, they would either have to gain 6 electrons or lose 2. It is easier to lose 2.
Group II elements (also called alkaline earth metals), have two valence electrons. To fill their outer shell, they therefore become ions with two positive charges, such as magnesium: Mg -> 2e- + Mg2+
Positive ions form when an atom or group of atoms loses one or more electrons.
