Why do the alkali metal have lower ionization energies than the 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 metal and alkaline earth metal have how many ionization energies?
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
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
Why the melting point boiling point and densities of alkaline earth metals are higher than alkali earth metals?
Alkaline earth metals do not exist , only alkali earth metals
Why Alkaline earth metals are harder than alkali metals?
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.
Is the alkali metal more reactive than an alkaline-earth metal?
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
Why do alkali metals have lower ionization energies than the alkali 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 metal and alkaline earth metal have how many ionization energies?
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
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
First ionisation energies of alkaline earth metals are higher than those of alkali metals?
Yes, they are.
Which group of the periodic table has the elements with lowest first ionization energies?
1A Alkali Metals
How many Alkaline and Alkali Metals are there?
Six alkali metals and six alkaline earths.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
Why ionization energies of alkaline earth metals decrease from Be to Ba?
as we know that there are 7 periods and 18 groups ,as we go down a group the size of the atom decreases therefore there is a decrease in ionization energy for
Do alkali metals react slower or faster than alkaline earth metals?
Alkali metals are more reactive than alkaline earth metals.
Is a metal an acid or alkali?
its definitley not acid Some metals are called alkali metals or alkaline earth metals because they often form alkaline compounds; but metals are not alkali or acids.
