What else can I help you with?
How would you expect Rubidium and caesium to react with water?
Rubidium and cesium are alkali metals located in Group 1 of the periodic table. They are highly reactive with water, producing hydrogen gas and forming metal hydroxides. The reaction with cesium is particularly vigorous, sometimes leading to explosions due to the rapid release of hydrogen gas.
What is the family name for the elements lithium sodium potassium rubidium and caesium?
The family name for lithium, sodium, potassium, rubidium, and caesium is the alkali metals. These elements are all found in Group 1 of the periodic table and share similar chemical properties, such as being highly reactive and easily forming ionic compounds.
What elements in addition to lithium makeup the alkali metal family?
The alkali metal family consists of the elements lithium, sodium, potassium, rubidium, cesium, and francium. These elements share similar chemical properties, including being highly reactive and forming alkaline solutions when they react with water.
Alkali metal hydroxides and alkaline earth metal hydroxides are?
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.
What are physical and chemical properties of rubidium?
Physical Properties : Colour State(liquid, gas and solid) Melting point Boiling point Density Chemical Properties : How it reacts with other things or substances.
Does alkaline reacts in water?
Yes, alkaline earth metals react with water forming their hydroxides.
Highly reactive metals?
All the ALKALI METALS are highly reactive. The alkali metals are a series of chemical elements forming Group 1 (IUPAC style) of the periodic table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
Will caesium chloride dissolve in water?
Yes, caesium chloride is soluble in water. It dissociates into cations (Cs+) and anions (Cl-) when dissolved in water, forming a colorless solution.
What happens to rubidium when it is exposed to air?
Rubidium reacts quickly with oxygen in the air, forming a yellow oxide coating on its surface. This oxide layer can catch fire spontaneously in air, so rubidium is usually stored under oil to prevent contact with oxygen.
What is the reactivity of rubidium?
Rubidium is highly reactive, readily reacting with water to release hydrogen gas. It is also reactive with oxygen and halogens, forming various compounds.
What elements did Mendeleev group with lithium in his periodic table?
alkaline metal group(or the group 1 elements, except for hydrogen(H), which is a group 1 element but not an alkali metal) - lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
What is sodiums family?
Sodium belongs to the alkali metal family on the periodic table. Members of this family have similar chemical properties, including being highly reactive with water and forming ionic compounds. Sodium is in the same group as elements like lithium and potassium.
