These elements are all alkali metals. They belong to the same group (Group 1) in the Periodic Table, have similar chemical properties, and react vigorously with water to form alkaline solutions.
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.
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.
In addition to hydrogen, all elements in Group I of the periodic table have one valence electron. They are lithium, sodium, potassium, rubidium, cesium, and francium. The farther you move right on the periodic table the more valence electrons. For example, elements in Group VII have 8 valence electrons except helium.
Iron is the odd one out because it is a transition metal, while lithium, potassium, and sodium are alkali metals.
Sodium (Na), Lithium (Li), or Potassium (K).
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)
The two most common alkali metals are sodium and potassium. They are found in many compounds and minerals, and are essential for various biological processes in living organisms.
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.
Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
these are in alkali metal groupsso the names are hydrogen, lithium, sodium, potassium, rubidium, caesium
sodium, hydrogen, rabidium, potassium,cesium, and francium
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.
Hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium have one valence electron.
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.
In addition to hydrogen, all elements in Group I of the periodic table have one valence electron. They are lithium, sodium, potassium, rubidium, cesium, and francium. The farther you move right on the periodic table the more valence electrons. For example, elements in Group VII have 8 valence electrons except helium.
Lithium, sodium and potassium are all in the first family.
Potassium and lithium.
