All alkali metals react with water, however them turning into a silver ball depends more on the initial shape. If it is of a cubic or spheric shape to start off with, it is likely to turn into or remain a ball shape.
In the most basic sense the metals in question are Lithium, Sodium and Potassium. These will stay long enough for the shape to be visible. Rubidium, Caesium and Francium could hypothetically turn into a silver ball but it would need to be a large sample to see this as, with the usual amount, the reaction is near instantaneous.
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water Example: ================ Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
Improve Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water
The pH of water changes after a reaction with an alkali metal because the metal reacts with water to produce hydroxide ions, increasing the concentration of hydroxide ions in the solution and making it more basic. This leads to a shift in the pH towards the alkaline side of the pH scale.
Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.

No, an alkali is a type of metal.

Alkali metals are famous for their vigorous reactions with water, and these reactions become increasingly violent as one moves down the group. The Reaction of Alklali metals as folow: Alkali metal + water → Alkali metal hydroxide + hydrogen gas
Potassium (K) is more reactive than silver (Ag). Potassium is an alkali metal on the far left side of the periodic table, making it highly reactive with water and oxygen. Silver is a transition metal that is more stable and less reactive compared to alkali metals like potassium.
Sodium chloride is dissociated in water in Na+ and Cl-. Sodium is an alkali metal.
Alkali metal hydroxides are strong bases that are highly water-soluble, forming alkaline solutions. Alkaline earth metal hydroxides are also bases but are less soluble in water compared to alkali metal hydroxides, resulting in less alkaline solutions.
Sodium is neither an acid nor an alkali in water. When sodium is dissolved in water, it forms sodium hydroxide (a strong alkali) and hydrogen gas. Sodium itself is a metal and is not considered acidic or alkaline in its pure form.
When an alkali metal like sodium or potassium reacts with water, it produces hydrogen gas. This reaction is highly exothermic and can be violent. The alkali metal displaces hydrogen from water molecules, leading to the formation of hydrogen gas and the corresponding metal hydroxide.
Metals react with water to form metal hydroxides and hydrogen gas. The reactivity of the metal determines the intensity of the reaction. Highly reactive metals like sodium and potassium react vigorously with water, while less reactive metals like copper and silver have a slower reaction rate.
