Study Notes
Alkali Metals
- The alkali metals are a group of elements in the Periodic Table.
- The alkali metals are also known as Group 1 elements.
- The main characteristic of the alkali metals is that they are very reactive and readily lose one electron to form a positive ion.
Non-Alkali Metals
- The noble gases, such as Helium (He), are not considered alkali metals.
Alkaline Earth Metals
- The alkaline earth metals are a group of elements in the Periodic Table.
- The alkaline earth metals are also known as Group 2 elements.
- The alkaline earth metals are less reactive than the alkali metals.
Origin of Names
- The alkali metals are called 'alkali' because they form alkaline solutions when they react with water.
- The alkaline earth metals are called 'alkaline' because they form alkaline solutions when they react with water.
S-Block Elements
- The s-block elements are a group of elements in the Periodic Table.
- The alkali metals and the alkaline earth metals belong to the s-block.
- The s-block elements are characterized by having one or two electrons in the outermost energy level.
Properties of S-Orbital
- The s-orbital can accommodate two electrons.
Lithium
- Lithium is the first element of the alkali metals.
