The answer is 2+
The alkali earth metals have a charge of +2. This is because they have two valence electrons which they lose to form ions with a 2+ charge, making them more stable. Examples of alkali earth metals include magnesium, calcium, and strontium.
Alkali earth metals react with oxygen to form basic oxides.
Alkaline earth metals are less reactive than alkali metals in the same period because they have higher ionization energies and are less likely to lose electrons. Alkali metals readily lose their outermost electron to form a +1 charge, whereas alkaline earth metals require more energy to lose their outermost two electrons to form a +2 charge.
Alkali metals are highly reactive, soft metals that readily lose their outermost electron to form ions with a +1 charge. They are located in Group 1 of the periodic table. Alkaline earth metals are also reactive, but less so than alkali metals, and they lose two electrons to form ions with a +2 charge. They are located in Group 2 of the periodic table.
Group 1 elements (alkali metals such as sodium, potassium) lose 1 electron to form ions with a +1 charge.

anion because they have -ve charge
Alkali metals are found in group 1 of the periodic table. They will form ions with a 1+ charge. If you meant alkaline earth, they are found in group 2, and will form ions with a 2+ charge.
Your Alkali Metals are those elements on the leftmost column of the periodic table (except for Hydrogen). Lithium (Li), Sodium (Na), Potassium (K), Rubidium, Cesium, Francium. You can remember them as those that form the Alkali bases, Sodium Hydroxide (NaOH), and Potassium Hydroxide (KOH) among others. In Pure Metallic form, they would have a neutral charge. However, they are frequently found in ionic form where they loose an electron to form a positive ion with a +1 charge. Li+ Na+ K+ etc.
alkaline earth metals and alkali metals have 2 and 1 electrons in their outer most shell and are not tightly bound to nucleus so they are ready to lose their outer most electrons to form mono and divalent cations.
The alkali metals are generally more reactive than the alkaline earth metals. They form 1+ ions while the alkaline earth metals form 2+ ions. Alkali metal compounds tend to be more soluble in water than alkaline earth metals.
Alkali and alkaline earth metals are too chemically reactive to stay in metallic form.
Group 1 elements (alkali metals such as sodium, potassium) lose 1 electron to form ions with a +1 charge.
Alkali metals have a +1 oxidation state and form compounds with a 1:1 ratio of metal to other element, while alkaline earth metals have a +2 oxidation state and form compounds with a 1:2 ratio. By analyzing the stoichiometry of compounds formed with these metals, you can distinguish between alkali metals and alkaline earth metals.
