2 electrons in the outermost shell.
i think its Barium
All atoms want to do is make their valence shell full. In alkali metals they have all of their shells completely full except one valence electron. The alkali metals REALLY want to get rid of that electron, so they will react with many elements/compounds to get rid of that electron. In alkaline earth metals they have all of their shells completely full except for two valence electrons. They also want to get rid of those electrons but the alkaline earth metals are not as desperate to do so as the alkali earth metals which make the alkaline much less reactive than the alkali metals.
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
You think probably at Unbinilium (120Ubn) an element not still obtained. The supposed electron configuration of Ubn will be [Uuo]7s2.
Barium has the largest electron affinity among the alkaline earth metals.
No, not all alkaline metals have 2 electron shells. Alkaline metals like lithium, sodium, and potassium have 2 electron shells, but alkaline earth metals like magnesium and calcium have 3 electron shells.
An element with a single electron in its highest energy level is likely an alkali metal. Alkali metals like lithium, sodium, and potassium have one electron in their outer energy level, making them highly reactive and likely to form ionic bonds.
Barium (Ba) is the alkaline earth metal with an electron configuration that ends in 6s2. Its full electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2.
All alkali metals, alkaline earth metals, and halogens have a common valence electron configuration: alkali metals have 1 valence electron, alkaline earth metals have 2 valence electrons, and halogens have 7 valence electrons. This shared electron configuration influences their chemical properties, such as reactivity and bonding tendencies.
The charge on any ion formed by an alkaline earth metal is typically +2. This is because alkaline earth metals readily lose two electrons to achieve a full outer electron shell and acquire a stable electron configuration.
2 electrons in the outermost shell.
they all have at least one electron

The charge on any ion formed by an alkaline earth metal is typically +2. Alkaline earth metals have two valence electrons that they can lose to achieve a stable electron configuration, resulting in a 2+ charge.
Alkaline earth metals are less reactive than alkali metals because they have two valence electrons, requiring more energy to remove compared to the 1 electron in alkali metals. This makes them less likely to form as many bonds with other elements. Additionally, alkali metals are stored in oil or inert gases to prevent them from reacting with moisture in the air, whereas alkaline earth metals are less prone to this level of reactivity.
Alkaline-earth metal ions typically have a charge of +2. This is because they lose two electrons to achieve a stable electron configuration, resulting in a 2+ charge. Examples of alkaline-earth metals include calcium (Ca2+), magnesium (Mg2+), and barium (Ba2+).
