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 else can I help you with?
When an alkali metal reacts with water it produces what?
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
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.
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.
An alkali metal which reacts with water vigorously with water and sends sparks flying?
Lithium is an alkali metal that reacts vigorously with water, producing sparks due to the release of hydrogen gas. This reaction is highly exothermic, leading to the formation of lithium hydroxide and hydrogen gas.

When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
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.
What is the metal that reacts slowly with cold water to form a hydroxide?
The metal that reacts slowly with cold water to form a hydroxide is magnesium. When magnesium reacts with water, it forms magnesium hydroxide and hydrogen gas.
What metal reacts in the air but slowly in the water?
copper
What happens when metal reacts with metal?

What reacts with an alkali to produce hydrogen gas?
When an alkali metal like sodium or potassium reacts with water, it produces hydrogen gas. This reaction is highly exothermic and can be violent. The alkali metal displaces hydrogen from water molecules, leading to the formation of hydrogen gas and the corresponding metal hydroxide.
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).
An alkali metal which reacts with water vigorously with water and sends sparks flying?
Lithium is an alkali metal that reacts vigorously with water, producing sparks due to the release of hydrogen gas. This reaction is highly exothermic, leading to the formation of lithium hydroxide and hydrogen gas.
What is grey metal that reacts with water?
Zinc is a grey metal that can react with water, although it does so slowly. When zinc reacts with water, it produces zinc hydroxide and hydrogen gas.
What does alkali form when it reacts with ammonia gas?
When an alkali metal (such as sodium or potassium) reacts with ammonia gas (NH3), it forms a complex called an amide. This reaction involves the alkali metal displacing hydrogen in ammonia to form metal amide and hydrogen gas.
What alkali metal reacts violently in water with a purple flame?
Potassium and dont try it at home it is dangerous
