What else can I help you with?
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.
What are characteristic property of the alkaline earth metals?
they are harder than alkali metals
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
Do alkali metals react slower or faster than alkaline earth metals?
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.
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
Low ionization energies are most characteristic of atoms that are?
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.
First ionisation energies of alkaline earth metals are higher than those of alkali metals?
Yes, they are.
How does the reactivity of an alkaline earth metal compare with that of alkali metal in the same period?
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.
What are metals that lose electrons easily called?
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.
Why alkali and alkaline earth metals easily form cations?
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.
Is alkali metal more reactive than transition metal?
Yes, alkali metals are more reactive than transition metals. This is because alkali metals have low ionization energies and readily lose their outermost electron to form positive ions, whereas transition metals have higher ionization energies and show a more variable reactivity depending on the particular metal and conditions.
Why Alkali metal and alkaline earth metal form cation?
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.
