Key Points
- Rubidium (Rb) is an element that belongs to the s-block of the periodic table.
- It is an alkali metal and is found in Group 1 of the periodic table.
- Rubidium has an atomic number of 37 and is characterized by having a single electron in its outermost s-orbital.
- Alkali metals, including Rubidium, are known for their high reactivity and are typically stored under oil to prevent reaction with air or water.
Additional Information
- s-block Elements
- The s-block elements are those in which the outermost electrons occupy an s-orbital. These elements are found in Groups 1 and 2 of the periodic table.
- Group 1 elements are known as alkali metals and include Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr).
- Group 2 elements are known as alkaline earth metals and include Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra).
- These elements are characterized by their high reactivity, especially with water, and they form basic (alkaline) solutions when they react with water.
- d-block Elements
- The d-block elements are those in which the outermost electrons occupy a d-orbital. These elements are found in Groups 3 to 12 of the periodic table.
- They are often referred to as transition metals and include elements like Iron (Fe), Copper (Cu), and Gold (Au).
- Transition metals are characterized by their ability to form variable oxidation states and colored compounds.
- They are also known for their catalytic properties and high conductivity of electricity and heat.
