Cesium. Cesium is the bad boy of the alkali metals, a period that's just jam-packed with seriously nasty elements. Cesium is reactive enough that if you were to put some water into dry ice, and wait till the ice got that cold itself before putting some cesium on it, the cesium would still react with it!
Here's a remembrance: the higher an alkali metal's atomic number, the more reactive it is.
it is about Caesium metal. it is reactive than others.
Potassium is the most reactive.
It is lithium.
Lithium
Caesium.
I believe that Fluorine is the most reactive of the elements. Lithium may be the most reactive metal, but don't forget potassium.
No. Lithium is the least reactive alkali metal. Within the same environment, potassium will tarnish at a faster rate.
Lithium is the 3rd element in the Periodic Table. It is an alkali metal (like Sodium and Potassium). It was first given the name "lithos", which in Greek means "stone", as it was discovered in a mineral; as opposed to sodium and potassium, which were discovered in plant tissue. Its name was later standardized as "lithium".
Reactivity of any metal depends on its capacity to loose electrons as quickly as possible. Among Lithium, Copper and tungsten, lithium is the most reactive since it looses electrons very quickly and forms its cation. In fact, it is among the most reactive metals.
Fe - which is the symbol for Iron. Li is Lithium Na is Sodium K is Potassium Lithium, Sodium, and Potassium are all Alkali Metals. Iron is a metal in the 1st transition series - quit a bit to the right of the alkali metals in the Period Table.
Reactivity increase down the group.Ceasium is the most reactive.
Any of the alkali metals: lithium, sodium, potassium, etc.
Yes, along with Sodium, Potassium, Rubidium, Cesium and Francium, Lithium is an alkali metal.
I believe that Fluorine is the most reactive of the elements. Lithium may be the most reactive metal, but don't forget potassium.
lithium, sodium, potassium, rubidium, cesium and francium
Iron rusts with water the more reactive metals react for the oxygen in a displacement the less reactive metals there is no reaction hope this helps x
Lithium(Li), Sodium(Na), Potassium(K), Rubidium(Rb), Cesium(Cs) and Francium(Fr) These are the group one metals known as alkali metals and are highly reactive with water.
Yes, the alkali metals are Lithium, Sodium, Potassium, Rubidium, Caesium and Francium.
Lithium is a metal, it reacts by losing an electron to form a positive ion. It is a member of Group 1 with sodium and potassium.
Lithium, sodium and potassium are in group I of the periodic table, which means they have a valency of 1. This makes them highly reactive with other elements, so when they are found they have most likely reacted with another element to form a compound.
Cesium is the most chemically reactive metal
No. Lithium is the least reactive alkali metal. Within the same environment, potassium will tarnish at a faster rate.
