Zn
Lithium reacts vigorously (but not violently) with water.
Yes. Calcium reacts vigorously with water producing hydrogen and calcium hydroxide.
When a metal oxide reacts with an acid a slat and water are formed.
Li does NOT react slowly with water. It reacts vigorously to produce LiOH + H2 gas.
Al2Br6 reacts vigorously with water with evolution of HBr and formation of Al-OH-Br species.
Potassium
It is a solid. It is half as dense as water. It is the least dense metal. It is highly reactive.It reacts vigorously with water, tarnishes rapidly in air and is flammable.hardest alkali but soft enough to be cut using a knife. :)
Sodium is a soft metal and can be cut with knife. Sodium metal is used in chemistry lab, sometimes in fireworks. Sodium when exposed to water, reacts vigorously.
Lithium reacts vigorously (but not violently) with water.
Yes. Calcium reacts vigorously with water producing hydrogen and calcium hydroxide.
When a metal oxide reacts with an acid a slat and water are formed.
Li does NOT react slowly with water. It reacts vigorously to produce LiOH + H2 gas.
Group one elements react vigorously with water.They even react when exposed to air.For example lithium reacts violently with water.
Exothermic
Al2Br6 reacts vigorously with water with evolution of HBr and formation of Al-OH-Br species.
Calcium hydroxide, traditionally called slaked lime is one.
