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
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.
No. The alkali and alkaline earth metals are very reactive.
It is not a alkaline metal.It is a alkaline earth metal.
Alkaline earth metals do not exist , only alkali earth metals
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
It is about first ionization energy. It is less than alkaline earth metals.
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.

Alkali metals react faster than alkaline earth metals due to their lower ionization energy and higher reactivity. Alkali metals readily lose their outermost electron to form a +1 cation, making them highly reactive with water and air. Alkaline earth metals, on the other hand, are less reactive as they have higher ionization energies and require more energy to lose their outer electron.
Low ionization energies are typically characteristic of atoms that have large atomic size and few protons in their nucleus, such as alkali metals and alkaline earth metals. These atoms have loosely bound electrons that require less energy to remove.
Alkali and alkaline earth metals easily form cations because they have low ionization energies and readily lose electrons to achieve a stable electron configuration. This results in the formation of positively charged ions (cations) with a noble gas electron configuration, which is energetically favorable.
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.
Yes, they are.
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.
No. The alkali and alkaline earth metals are very reactive.
Alkali metals and alkaline-earth metals react violently with water or air because they have low ionization energies, meaning they readily lose electrons to form positive ions. When they react, they release a large amount of energy as heat and produce hydrogen gas. This rapid release of energy and gas can result in explosions or violent reactions.
Metals that lose electrons easily are called "reactive metals" or "electropositive metals." These metals have low ionization energies, which allow them to readily give up electrons to form positive ions.
