Lithium (Li) is the alkali metal that reacts most slowly with water. It is the first alkali metal and thus, the least reactive of the group. The lithium metal is seen to dart around the surface of the water with some whzzing and effervescence of hydrogen gas. The heat produced from the reaction may not be sufficient to ignite the hydrogen gas, resulting in no flame, compared to other metals like sodium and potassium where the reaction would be more violet and the metal would quickly catch fire.

What metal burns in air but only reacts slowly in water?
It depends what you mean by slowly! Calcium burns in air and reacts fairly quietly with water, certainly much more slowly than the alkali metals do.
When an alkali metal reacts with water it produces what?
Hydrogen
An alkali metal which reacts with water vigorously with water and sends sparks flying?
Potassium
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.
What metal reacts with water to cause an explosion?
there are some alkali metals. It can be sodium or potassium.

Metal that bursts into flames when it reacts in water?
I believe that you think to alkali metals (ex. sodium).
What alkali metal reacts violently in water with a purple flame?
Potassium and dont try it at home it is dangerous
What is the alkali metal in table salt?
the alkali metals bases reacts with the acids to form salt and water example NaOH+HCl=H2O+NaCl
What substance reacts with water to give a solution of pH value greater than 7?
For example an alkali metal.
Why sodium carbonate being a salt acts as an alkali metal?
It is not an alkali metal, but it is alkaline. The carbonate ion is a weak base; it reacts with water in small amounts to form bicarbonate ions and hydroxide ions.
Which metal burns in air but only react very slowly with water?
Copper burns and reacts in the air to form copper oxide, however i htink it reacts very slowly with water. Hope that helped ;)
