The element found in Group 6 (or VIA using older numbering) and Period 5 of the periodic table is Molybdenum (Mo).

Understanding the Periodic Table

The periodic table organizes chemical elements based on their atomic number, electron configuration, and recurring chemical properties. Elements are arranged in rows (periods) and columns (groups).

• Periods: Rows represent the energy levels of electrons within an atom. Period 5 indicates that molybdenum atoms have electrons occupying five principal energy levels.

• Groups: Columns represent elements with similar outer electron shell configurations. This leads to similar chemical behaviors. Group 6 elements are characterized by having six valence electrons.

Properties of Molybdenum (Mo)

Molybdenum is a hard, silvery-grey, and lustrous transition metal. Here are some key properties:

• Atomic Number: 42
• Atomic Symbol: Mo
• Atomic Weight: 95.96 g/mol
• Melting Point: 2623 °C (4753 °F)
• Boiling Point: 4639 °C (8382 °F)
• Valence Electrons: 6

Uses of Molybdenum

Due to its high melting point and excellent strength, molybdenum finds applications in numerous industries:

• Alloys: It is a crucial component in high-strength steel alloys used in automotive parts, tools, and machinery. The addition of molybdenum significantly increases the strength and toughness of steel.

• Catalysis: Molybdenum compounds act as catalysts in various chemical processes, including petroleum refining and the production of ammonia.

• Pigments: Certain molybdenum compounds are utilized as pigments in paints and plastics.

• Electronics: Molybdenum is employed in electronic components due to its high conductivity and resistance to corrosion.

Other Group 6 Elements

It's worth noting that other elements reside in Group 6, each with distinct properties:

• Period 2: Oxygen (O) – A nonmetal crucial for respiration.
• Period 3: Sulfur (S) – A nonmetal commonly found in various compounds.
• Period 4: Chromium (Cr) – A transition metal known for its use in stainless steel.
• Period 6: Tungsten (W) – A transition metal with an extremely high melting point, used in light bulbs.

Conclusion

In summary, molybdenum (Mo) is the element located in Group 6 and Period 5 of the periodic table. Its unique properties make it a valuable component in various industrial applications. Understanding the periodic table's organization helps us understand the relationships between elements and predict their behavior.
