Because the positive ions mix together to make them unstable
What else can I help you with?
Which group of metals is more reactive the alkali metals or the alkaline earth metals?
The alkali metals are more reactive.
Are alkaline-earth metals reactive?
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
What family of elements is very reactive to water?
Alkali metals and earth alkali metals do react strongly with water.(Lithium, ..., Caesium) (Beryllium, ..., Barium)
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
What metal is alkali metal?
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
Which group of elements are very reactive with water?
The column you're looking for is called the Alkali metals. They are very reactive, but not JUST with water. They actually violently react with almost ANYTHING if they aren't already with another element. Exposure to air, skin, dirt, other metals, It all ends with violence (i.e. huge explosions).
How chemically active are alkali metals?
Alkali metals are the most reactive metals.
What are more reactive alkali metals or alkline earth metals?
alkali metals
What type of metal such as sodium have a single valence electrons and are very reactive?
Highly reactive metals with one valence electron are known as Alkali metals.
What are metals that are less reactive than alkali metals and alkaline-earth metals?
Transition metals such as copper, silver, and gold are less reactive than alkali metals and alkaline-earth metals. These metals are less likely to react vigorously with water or air compared to alkali and alkaline-earth metals.
How are alkali metals different any from other metals?
Alkali metals are very reactive metals.
What are the group of soft silvery reactive metals known as?
alkali metals
