Currently, 70 metals are known among the total elements identified on the periodic table.
Understanding Metals in the Periodic Table
Metals constitute a significant portion of the chemical elements and are generally found on the left side of the periodic table. These elements are characterized by their distinct properties, such as luster, malleability, ductility, and excellent conductivity of heat and electricity. Out of a total of 92 naturally occurring elements, 70 are classified as metals.
Types of Metals
Metals are broadly categorized into several groups based on their chemical properties and position in the periodic table. The five main kinds of metals include:
- Alkali Metals: Highly reactive metals found in Group 1 (e.g., Lithium, Sodium, Potassium).
- Alkaline Earth Metals: Reactive metals found in Group 2 (e.g., Magnesium, Calcium, Barium).
- Transition Metals: Large group of elements in the d-block, known for their variable oxidation states and colorful compounds (e.g., Iron, Copper, Gold, Silver).
- Lanthanides (Rare Earth Elements): A series of 15 metallic chemical elements with atomic numbers from 57 (Lanthanum) to 71 (Lutetium), typically placed below the main body of the periodic table.
- Actinides: A series of 15 metallic chemical elements with atomic numbers from 89 (Actinium) to 103 (Lawrencium), also typically placed below the main body of the periodic table, many of which are radioactive.
Metal Count at a Glance
To provide a clear overview, here's a breakdown of the number of elements and metals:
| Category | Number of Elements |
|---|---|
| Total Elements | 92 |
| Total Metals | 70 |
This classification helps in understanding the diverse chemical behaviors and applications of these fundamental materials.
