Alkali metals are very reactive metals.
alkali metals
The alkali earth metals act in a similar but slightly less reactive way to alkali metals
Alkali metals are very reactive and soft.
Because they are all alkali-metals and alkali -metals are known for being very reactive.
Cesium is the most chemically reactive metal
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
All the alkali metals (Li, Na, K, Rb, Cs, Fr) are very reactive.
The alkali metals are more reactive.
It is not true; some metals are not so reactive and noble metals are practically unreactive.
No. The alkali and alkaline earth metals are very reactive.
Alkali metals are the most reactive metals.
alkali metals
Highly reactive metals with one valence electron are known as Alkali metals.
The most reactive groups are alkali metals and halogens.
The Alkali metals are the most reactive group of metals in the periodic table. Of these Francium is the most reactive metal of all.
The alkali earth metals act in a similar but slightly less reactive way to alkali metals
