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.


Why alkali metals are more reactive than alkaline earth metals?

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 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


Which alkaline earth metal is the most likely to attract an electron pair?

The electronegativityÊ of alkaline earth metals decreases as you go down the group due to increase in atomic radius. The earth alkaline metals are beryllium, magnesium, strontium, barium and radium. Radium has the smallest electronegative.


Do alkaline earth metals form ions with a plus 2 charge?

YEP! remember In science in order for the Alkali metals and Alkaline earth metals to become stable they must give AWAY electrons. The Earth metals have a Plus 2 charge because they give away 2 electrons on there outer shell!

What is the general valence electron ground state electronelectron configuration for neutral alkaline earth metals?

What characteristic does the alkali metals alkaline earth metals and the halogens have in common?

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.


Which metals forms ions with a noble gas electron configuration?

Transition metals such as copper, silver, and gold can form ions with a noble gas electron configuration. This occurs when they lose electrons to achieve a stable electron configuration similar to the nearest noble gas.


What element is an alkaline earth metal whose electron configuration ends in 6s2?

All alkaline earth metals have electron configurations ending in s2; 6s2 would be the alkaline earth metal in period 6 of the PTE, which is barium.


What is the oxidation number in Alkaline Earth Metals?

The oxidation number of alkaline earth metals is typically +2. This is because they have two valence electrons, which they tend to lose to achieve a stable electron configuration.


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.


What group achieves the electron configuration of a noble gas by gaining one electron?

All halogens have 7 valence electrons. They gain one electron and achieve noble gas electronic configuration


Do all alkaline metals have 2 electron shells?

No. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two shells.


Metals with two electron in the outer level?

Valence electron configuration common to all elements of alkaline earth metals?

Be (berylium) berylium Mg (magnesium) magnesium Ca (calcium) calcic Sr (strontium) strontium Ba (barium) baryum Ra (radium) radium All the elements' general valence electron configuration is ns2 "n" is a number from 2 (for Be) to 7 (for Ra).


Explain why alkali metals have a greater affinity for electrons than alkaline earth metals?

They don't, they actually have a greater tendency to lose electrons. This is for a number of reasons. First of all, the alkali metals form a stable cation by losing one electron, while the alkaline-earth metals need to lose two to form a stable ion. It takes more energy to remove one electron from an atom than it does to remove two. Additionally an alkaline earth metal has a greater positive charge on its nucleus and a smaller atomic radius than an alkali metal in the same row of the periodic table. This make it even harder to remove valence electrons. ------------ ?? WRONG: Alkali metals have a valence electron configuration of ns1 so they can accept another electron in the ns orbital. On the other hand, alkaline earth metals have a valence electron configuration of ns2. Alkaline earth metals have little tendency to accept another electron, as it woudl have to go into a higher energy p orbital.


What is one property of alkaline metals?

One property of alkaline metals is that they are highly reactive, readily forming ionic compounds with other elements due to their tendency to lose electrons and achieve a more stable electron configuration.
