It means metals that are highly reactive. It's one of the most self-evident pieces of terminology in all of chemistry.
Perhaps you were trying to ask which metals are considered "highly reactive", which is a separate question, and one that to some extent depends on your definitions, but would certainly at minimum include all the alkali metals, maybe the alkaline earth metals, and possibly a few selected others (aluminium, for example... we don't usually think of aluminium as "highly reactive" because it immediately forms a thin transparent protective layer of aluminium oxide when exposed to air, but without that layer, it is indeed pretty reactive).
What else can I help you with?
What is the group of very reactive metals called?
Assuming "very reactive" to mean spontaneous and energetic in reaction, lower Alkaline metals are among the most reactive.
What are the ranks of the periodic table families from most to least reactive?
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Which group of metals is more reactive the alkali metals or the alkaline earth metals?
The alkali metals are more reactive.
What family in the Periodic table contain the most reactive metals?
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
Are alkaline-earth metals reactive?
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.
What is the different between reactive and non reactive metals?
one reacts and one doesn't
What do very reactive metals lose?
Reactive metals lose electrons when being oxidised.
Where are the most reactive non metals?
The most reactive non metals are Halogens which may combine most of the metals as well as non metals.
What is the most reactive group of metals in the periodic table is the?
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
How many reactive metals are there?
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.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
What family of the most reactive group of metals in the periodic table?
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
