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.
What else can I help you with?
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.
What is a characteristic property of alkaline earth meatls?
One characteristic property of alkaline earth metals is their tendency to form 2+ cations during chemical reactions. They also have relatively low electronegativity and reactivity compared to alkali metals.
Why do all the alkaline earth metals have similar properties?
All alkaline earth metals loss two electrons.
Which are products of the alkaline and earth alkaline metals combustion?
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
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.
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
Are ions of alkali metals larger or smallest than ions of alkaline earth metals from the same period?
Ions of alkali metals are generally larger than ions of alkaline earth metals from the same period because alkali metals have only one outer electron, leading to a larger atomic radius and therefore a larger ion size compared to alkaline earth metals, which have two outer electrons.
Is alkaline earth metal in the group of metals nonmetals metalloids or diatomic molecule?
The alkaline earth metals are metals!
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
Which alkaline earth metals are radioactive?
Radium is the radioactive metal among alkaline earth metals.
What are the key differences between alkaline earth metals and alkali metals?
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.
