Tin, gold, silver, copper, iron, lead, aluminum, are there any other metals I don't know about? What are the metallic elements? What are their properties?

Besides tin, gold, silver, copper, iron, lead and aluminum, there are many other metallic elements. The following are some common metallic elements and their properties:

Platinum: Platinum is a precious metal with high corrosion and heat resistance, and is commonly used in jewelry, chemical catalysts and electronic equipment.

Molybdenum (Molybdenum): Molybdenum is a high melting point metal, high hardness, good heat resistance and corrosion resistance, commonly used in the preparation of alloys and electronic equipment manufacturing.

Germanium (Germanium): germanium is a semiconductor metal, electrical conductivity between the conductor and insulator, commonly used in optoelectronic devices and semiconductor manufacturing.

Titanium: Titanium is a lightweight metal with excellent strength and corrosion resistance, and is widely used in aerospace, medical implants and chemical industries.

Nickel: Nickel is a silvery-white transition metal with good ductility and magnetism, and is used in a wide range of applications such as alloy preparation, batteries and chemical catalysts.

Vanadium (Vanadium): Vanadium is a hard transition metal with corrosion resistance and good strength, and has important applications in steel preparation, catalysts and batteries.

Lithium: Lithium is a light metal with low density and good conductivity properties, widely used in battery manufacturing.

The above are only some of the metallic elements, there are many other metallic elements present. The nature of each metal element depends on its atomic structure and chemical properties, and has its own unique uses and characteristics in different applications.
