The alkali metals easily yield the one electron found in their valence shell, to bond with other elements. Since it takes so little energy to remove this electron from an alkali metal (i.e., they have a low ionization energy) these metals are never found in nature in their elemental forms (they are too reactive; i.e., their atoms so easily bond to other atoms).
Alkali metals
Highly reactive metals with one valence electron are known as Alkali metals.
Yes, alkali metals will react with anything to get rid of that one valence electron, which makes them highly reactive.
alkali earth metals
All transition metals have valence electrons in a d-orbital.
They are one valence electrons and are the most reactive group of metals in the periodic table.
Highly reactive metals with one valence electron are known as Alkali metals.
Highly reactive metals with one valence electron are known as Alkali metals.
Alkali metals
No. Alkali metals have one valence electrons. Halogens have 7 valence electrons.
Elements become less reactive as you move from left to right across the periodic table. This is due to how many valence electrons (outer-most electrons) the element has; the less valence electrons, the more reactive the element.
A metal in the alkali metal family has one valence electron where as a metal in boron family has three valence electrons. It is easy to remove one valence electrons than three. So alkali metals will be more reactive.
