Alkaline Earth metals are the elements in group 2 of the Periodic Table. They include beryllium, magnesium, calcium, strontium and barium. Radium is unstable as it is radioactive.
yes, all with a charge of 2+
larger
the group number
It is because alkali metals are larger in size than alkaline earth metals.Also, the effective nuclear charge is more in case of alkaline earth metals. This makes their ionization enthalpies larger than alkali metals.
They all have a one ,charged ion.All form +2 ion.
Alkaline earth metals are in the 2nd column of the periodic table. They can lose up to 2 electrons without having to pull electrons out of an inner shell, and so alkaline earth metals almost always have a charge of +2
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 metals and alkaline earth metals will form ions (by losing 1 and 2 electrons respectively) with noble gas electron configuration.

They have two valence electrons and they form ions with a +2 charge.
All alkaline earth metal ions have a charge of +2
Alkali metals, like all other metals, form positive ions. The atom, in order to achieve octet structure, loses the 1 valence electron to the environment. Thus, it will have 1 less electron than the element should, and as a result form a 1+ charged ion.
