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.
How do the alkali metals differ from the alkaline earth metals?
alkali metals have one valence electron, whereas alkaline earth metals have two valence electrons.
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.
Why are the alkaline-earth metals less reactive than the alkali metals?
Alkaline-earth metal have two electrons in there outer shell, so only need to lose one to form a stable electron arrangement. Alkali metals have one electron in there outer shell - so they need only lose one to form a stable electron arrangement
What is the name of the group of elements with two valence electron in each period?
The name of the group of elements with two valence electron in each atom is "alkaline earth metals."
What element that increasing electron affinity?
rare earth elements
What is the characteristics of alkaline?
* alkaline metals contain the higher melting and also the boiling points. * These metals are present in the earths crust which does not have a basic form. * Alkaline earth metals are distributed in structure which is named as rock. * These metals have density which is low. * Alkaline earth metals have low electron affinity and as wells as low electronegativity. * One of the basic characteristic is, it contains two electrons in their outer shell.
Which of the alkaline earth metals is the largest?
Radium

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.
Which group will have an electron configuration that ends in s2?
The alkaline earth elements electron structure end in s2
How do the alkali metals differ from the alkaline earth metals?
alkali metals have one valence electron, whereas alkaline earth metals have two valence electrons.
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.
What is the general electron configuration for alkaline earth metals?
2 electrons in the outermost shell.
What is the important characteristic do the alkali and alkaline earth metals have in common?
they all have at least one electron
Which alkaline earth metal forms an ion with the same electron confirguration as krypton?
i think its Barium
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.
