When Group 2A elements form ions they lose the electrons in their outer shell. In doing so they form positive ions known as cations.
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.
Group 2A * Known as Alkaline earth elements * All are metals * Occur only in compounds * React with oxygen in the general formula EO (where O is oxygen and E is Group 2A element)
There are six elements in group 2A A group is a vertical column. The group consists of Be , Mg, Ca ,Sr, Ba , and Ra.
Group 6A elements have a higher electronegativity and a greater tendency to gain electrons to achieve a stable octet configuration. In contrast, Group 2A elements have a lower electronegativity and typically lose electrons to form cations.
Group 2A elements form compounds that are less soluble in water. Group 2A elements are harder. Group 2A elements have an additional valence electron. Group 2A elements are less reactive.

Group 2A elements tend to GAIN electrons!!

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.
These metal may lose two electrons.

Yes
bilat
Basically any element with a positive atomic number because all the electrons are paired. Ex: Group 2A, Group 4A, group 6A, and group 8A. the ions would all be paramagnetic though.
