37 (Rb)?
Rubidium
What is rubidium in periodic table?
Rubidium is a chemical element that is represented by the symbol Rb on the periodic table. It is a soft, silvery-white alkali metal with atomic number 37. Rubidium is highly reactive and is commonly used in research applications and in some specialized devices such as atomic clocks.
What sound does rubidium make if you hit it?
A dull thud as it is a very soft metal, rather like putty.
What reactive rubidium?
it is a soft metal that reacts with water (and acid) look on left side of periodic table
What are some of the characteristics of the element Rubidium?
The element Rubidium is part of the alkali metals group and is silvery-white and soft. It has a melting point of about 40 degrees celsius and a boiling point of 696 degrees celsius. It can ignite randomly in air and reacts violently with water. It can form amalgams with mercury and its flame is a yellowish purple.
What is the appearance of rubidium?
it is black coloured from outside and shiny from the inside
What is the macroscopic sample of rubidium?
A macroscopic sample of rubidium refers to a quantity of rubidium that is large enough to be observed and measured without the need for specialized equipment, typically weighing several grams or more. Rubidium is a soft, silvery-white alkali metal that is highly reactive and can be found in nature in trace amounts in minerals like lepidolite. In its pure form, rubidium can be obtained through the reduction of rubidium chloride with metallic potassium. Due to its reactivity, a macroscopic sample must be stored under oil or in an inert atmosphere to prevent oxidation.
