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 metals found as pure elements in sea water?
Alkali metals exist only as salts.
Why is group 1 metals called alkali metals?
They're metals that form alkaline compounds when they react with water.
Does water react with alkali metals vigorously?
Yes
What happens when metal reacts with metal?
Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.
Two metals that will float on water and react very quikly to form an alkalis?
Such metals are Sodium and Potassium (and all the alkali metals).
How do alkali metals react to cold water?
alkali metals react violently in cold water
What are the reactions with alkali metals and water like?
1) Alkali metals are stored in oil to minimise reaction with oxygen or water, it's a physical barrier towards air but the alkali metals still gradually corrode a traces of oxygen and water diffuse through. The reaction of alkali metals with water gets more violent for elements lower in the group e.g. (Li < Na < K < Rb < Cs). Adding them to water will cause an explosion due to the extremely exothermic nature of reaction, and can be rather dangerous and some alkali metals can react violently with just moisture in the air. Most of the alkali metals float on the top of the water, depending on how big the alkali metal is determines the size of the reaction this is because they're less dense that water itself and also during the reaction the alkali metals give of hydrogen gas which is quite flammable. Alkali Metal + Water » Metallic Hydroxide + Hydrogen The francium would be like any other alkali metal, it would be very violent like the other alkali metals.

Why are group 1 metals knowns as alkali metals?
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
Are alkali metals found as pure elements in sea water?
Alkali metals exist only as salts.
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
What are Two reactive metals that float in water?
The alkaline metals react with water, and Lithium and Sodium float on the water whilst reacting.
Why is group 1 metals called alkali metals?
They're metals that form alkaline compounds when they react with water.
Why the elements of Group 1 are generally known as alkali metals?
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
