Alkali metals have only 1 electron in their outermost (ultimate) shell. This means the atom needs energy to loose only one electron to have a completely filled outermost shell.
Other atoms with 2 or 3 electrons would have needed more than twice or thrice the energy than these to loose electrons.
Hence alkali metals are highly reactive compared to others.
Like alkali metals, who need to LOOSE 1 electron to have a completely filled outermost shell, halogens need to GAIN 1 electron to have a completely filled outermost shell. With the same theory mentioned above, they are highly reactive.
Alkali metals are very reactive metals.
Alkali metals are very reactive and soft.
Because they are all alkali-metals and alkali -metals are known for being very reactive.
The alkali metals have a low electronegativity and they easily loss an electron.
They are very reactive
Alkali metals are very reactive metals.
No. The alkali and alkaline earth metals are very reactive.
Alkali metals are very reactive metals.
Highly reactive metals with one valence electron are known as Alkali metals.
Alkali metals are very reactive and soft.
Because they are all alkali-metals and alkali -metals are known for being very reactive.
Highly reactive metals with one valence electron are known as Alkali metals.
group 1, alkali metals
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
The alkali metals have a low electronegativity and they easily loss an electron.
This is the first column in the Periodic Table. There are six metals that are "Alkali Metals" and six that are "Alkali Earth Metals". The Alkali metals are:LithiumSodiumPotassiumRubidiumCaesiumFranciumThese metals get more reactive as you go down the list...Hope I helped :D
