It's basically an indication of what metals are capable of displacing others. There's a list called the "reactivity series", and any metal on the list will displace anything lower on the list and be displaced by anything higher on the list.
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
The alkali metals are more reactive.
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
Alkaline-earth metals are less reactive compared to alkali metals, but they still react with water and oxygen to form oxides and hydroxides. They are more reactive than transition metals but less reactive than alkali metals.
one reacts and one doesn't
Reactive metals lose electrons when being oxidised.
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
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.
No. The alkali and alkaline earth metals are very reactive.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
Alkali metals are very reactive metals.
