one of them fizzes in the water and moves around really fast, the other one sinks and fizzes and last but not least i think "k" lights up in the red water!
Li (Lithium), Na (Sodium), K (potassium). They are highly reactive - they react violently with water and also react with oxygen.
Most metals do not react with water, especially at room temperature. It is easier to state which metals DO react with water. Those would be Li, K, Sr, Ca and Na. Those reacting with hot water (steam) would be Mg, Al, Zn and Cu. Most other metals do NOT react with water.
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)
k
there are some alkali metals. It can be sodium or potassium.
Alkali metals: Li, Na, K, Rb, Cs, Fr.

All of the 1st group metals (Li, Na, K, Rb, Cs, Fr) because they react with the air and many other things.
k
Lithium, sodium and potassium are all group I elements. They are also called alkali metals. They react violently with water to form strongly alkaline solutions. The elements, as we descend the group in the periodic table, become increasingly reactive.Li Na K are alkali metals. They are present in group-1. They have one valence electron.All of these elements are located in group 1 of the periodic table. Each of these elements are highly reactive metals. They react with acids to produce salts. All of these are good conductors of electricity and heat.Li,Na and K are in the 1st group of the periodic table. They are alkaline metals. They all have a valency of 1.
All of them except for Li, Na, K, and the ones that are gaseous at room temperature.
K
Li, Na, K, NH4
Rb (Rubidium) is the largest element among Li, Na, Rb, and K as you move down the same group or in the same period from left to right on the periodic table.
Rb > K > Na > Li. The order based on atomic size is Rb > K > Na > Li. Therefore, the size of the circles should reflect this order from largest to smallest.
