Lithium, sodium, and potassium react vigorously with water to form hydroxides and release hydrogen gas. The reactivity increases as you go down the group from lithium to potassium, with potassium being the most reactive.
i think the element will be lithium that's what i think
Sodium and potassium metals will burn violently when mixed with water, forming alkaline hydroxides and hydrogen gas. When mixed with kerosene, a hydrocarbon mixture, the reaction does not occur as kerosene is not reactive with these metals.
One key difference is the rate of reaction - potassium will react more vigorously and produce more heat compared to lithium. Another difference is that the reaction of potassium with water will produce more hydrogen gas compared to lithium's reaction.
Most don't, but a few do. Na and K come immediately to mind ie the Alkali Metals.
Two elements that can float on water are lithium and potassium. These elements have a lower density than water, which allows them to float on its surface.
Three metals that react with cold water are sodium, potassium, and lithium. These alkali metals react vigorously with water, producing hydrogen gas and corresponding hydroxides. Sodium reacts to form sodium hydroxide, while potassium reacts more violently, leading to the production of potassium hydroxide. Lithium reacts more slowly compared to the other two but still produces lithium hydroxide and hydrogen when in contact with cold water.
Sodium metal can react violently with water to produce sodium hydroxide and hydrogen gas, which can cause burns if it comes in contact with skin.
Lithium, sodium, potassium. rubidium, cesium, francium, calcium, strontium, barium and radium all react with varying degree of vigor with water to produce hydrogen gas. Other metals also will but not as vigorously.

Potassium, sodium, and lithium are the most reactive metals to water from the options provided. They react vigorously with water, producing hydrogen gas and forming alkaline hydroxides. Calcium and magnesium are less reactive compared to the other three metals when exposed to water.
They explode and combust.
Potassium, sodium, and lithium are the three most reactive metals in order. They react vigorously with water to produce hydrogen gas and hydroxide ions.
The word equation for the reaction of Li, Na, and K with H2O is: Lithium (Li) + Water (H2O) → Lithium hydroxide (LiOH) + Hydrogen gas (H2) Sodium (Na) + Water (H2O) → Sodium hydroxide (NaOH) + Hydrogen gas (H2) Potassium (K) + Water (H2O) → Potassium hydroxide (KOH) + Hydrogen gas (H2)
Very active metals which are on top of the electro-chemical series like sodium can react with water to release hydrogen.
Alkali metals like sodium, potassium, and lithium are highly unstable when combined with water, as they react violently to produce hydrogen gas and can cause explosions. Similarly, certain alkaline earth metals like calcium and magnesium can also react vigorously with water, though less explosively than alkali metals.
Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium are the main alkali metals, which all react fairly spectacularly with water (Cesium must be kept in argon gas to stop it reacting with air).
Ceasium will explode and create hydrogen gas and ceasium hydroxide. Ceasium react with water similary to other alkali metals (lithium, sodium, potassium, rubidium)
