Reactive metals lose electrons when being oxidised.
Alkali metals are very reactive metals.
Alkalis have one electron in their valency shells. They can "lose" this electron easily, forming a cation which is strongly reactive.
Assuming "very reactive" to mean spontaneous and energetic in reaction, lower Alkaline metals are among the most reactive.
No. The alkali and alkaline earth metals are very reactive.
There are five reactive metals: lithium, sodium, potassium, rubidium, and cesium. These metals are located in Group 1 of the periodic table and are highly reactive due to their tendency to lose an electron easily.
These metals lose easily an electron.
Alkali metals and alkaline earth metals have 1 and 2 valence electrons respectively. If they lose these electrons, they will get the electronic configuration of the nearest noble gas (stable octet configuration) and hence they are very reactive.
one reacts and one doesn't
one is its the first colom in the Periodic Table:}
Alkali metals are very reactive metals.
Hydrogen
Electronegativities of metals are very different: alkali metals are very reactive, platinum metals very unreactive. Metals react with nonmetals.
