- Actinides.
- Transition metals.
- Post-transition metals.
What is an example of a main group metal?
The metals that occur in Groups 1, 2, and 13–15 in the periodic table are called the main-group metals. The alkaline-earth metals—beryllium, magnesium, calcium, strontium, barium, and radium—occur in Group 2 in the periodic table (Figure I.
What is a characteristic of all metals?
All metals except for mercury are solids at room temperature. Many metals are shiny, ductile, and malleable. Most are also good conductors of heat. Electricity is a flow of electrons.
Is in a main group metal?
All transition elements are metals, but main group elements are classified into metallic and nonmetallic elements. Germanium and polonium may also be included as metals. Boron, silicon, germanium, arsenic, antimony, selenium, and tellurium exhibit some metallic characteristics and they are sometimes called metalloids.
What are the 3 types of metals?
There are three main types of metals ferrous metals, non ferrous metals and alloys. Ferrous metals are metals that consist mostly of iron and small amounts of other elements. Ferrous metals are prone to rusting if exposed to moisture.
What is another name for main group elements?
The main group elements, along with a few light transition metals, are the most abundant elements in the universe, solar system, and on Earth. For this reason, main group elements are sometimes known as representative elements.
Is RN a main group metal?
The main-group metals usually form charges that are the same as their group number: that is, the Group 1A metals such as sodium and potassium form +1 charges, the Group 2A metals such as magnesium and calcium form 2+ charges, and the Group 3A metals such as aluminum form 3+ charges….Metals, Metalloids, and Nonmetals.

What are the 10 properties of metals?
Physical Properties of Metals:
- Metals can be hammered into thin sheets.
- Metals are ductile.
- Metals are a good conductor of heat and electricity.
- Metals are lustrous which means they have a shiny appearance.
- Metals have high tensile strength.
- Metals are sonorous.
- Metals are hard.
What are the five characteristics of metal?
Metals are lustrous, malleable, ductile, good conductors of heat and electricity.
Is gold a main group element?
The metals in group IB (copper, silver and gold) are sometimes called the coinage metals. The columns with A (IA through VIIIA) are called the main group elements. The elements can also be divided into two main groups, the metals and the non-metals.
Is aluminum a main group metal?
aluminum (Al), also spelled aluminium, chemical element, a lightweight silvery white metal of main Group 13 (IIIa, or boron group) of the periodic table. Aluminum is the most abundant metallic element in Earth’s crust and the most widely used nonferrous metal.
What are the 10 uses of metals?

- Gold, Platinum and silver are used as jewelleries and ornaments.
- Iron and steel are used for construction purpose.
- Aluminium, steel are used as utensils.
- Mercury is used in thermometer and helps to check the temperature.
- Aluminium are used as insulation wires.
