reactive metals are typically contained in the alkali metal catagory. these can be dangerous because the give away their vallence electron to the H2O molocule causing and increase in heat and also the seperation of the atoms. in simple terms, these alkali metals explode on contact with water. lithium is the least reactive, then sodium, then potassium, then rubidium, then cesium. throwing larga amounts of these in water too close to you can result in death by explosion
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Alkali metals are very reactive metals.
Assuming "very reactive" to mean spontaneous and energetic in reaction, lower Alkaline metals are among the most reactive.
alkali metals
The most reactive metals are the alkali metals in group 1a.
Metals such as sodium, potassium, and calcium are highly reactive with acids and can undergo vigorous reactions, releasing hydrogen gas. These reactions can be dangerous and should be conducted with caution.
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
Dilute acid should not be added to reactive metals because the result is dangerous. This violent reaction can easily cause damage to property or cause harm to people.
The alkali metals are more reactive.
Alkali metals are most reactive metals. Halogen family comprises of highly reactive non-metals.
No. Gold is one of the least reactive metals and is so safe that for decades it was used as a dental filling.
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.
