VR Tour For Std. 10 Ch. 3. Metals and Non-metals
What's Included in Virtual tour of this chapter
Metal is a solid material that is typically hard, shiny, malleable, and ductile, with good electrical and thermal conductivity. Metals are good conductors of heat. The physical properties of the metal are it is Hard, lustrous, malleable, ductile, sonorous. We will also learn about the chemical properties of metals. We will also learn about the reactivity of metals. . Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. There are various other methods to prevent corrosion of metal, plain method, electroplating, etc.
Virtual tour 1: Physical Property of Metal: Good Conductors of Heat
Metal is a substance that is usually hard and shiny and electricity can pass through it easily. In this virtual tour, we will learn how metals are good conductors of heat. We will learn through an experiment how aluminum, as well as all the metals, is a good conductor of heat, as it easily conducts heat from one end to the other.
Virtual tour 2: Electric conductors
We will learn that how metals are a good conductor of electricity through an activity. We would require a metal wire, a piece of rubber, an iron nail, a piece of wood, and a piece of copper, graphite, and diamond. Metal wire, iron nails are good conductors of electricity whereas pieces of rubber and piece of wood are not good conductors of electricity. Graphite makes an exception even though it is a non-metal it is a good conductor of electricity.
Virtual tour 3: Chemical properties of Metal
In this virtual tour, we will learn about the chemical properties of metals. The metal shows a definite chemical reaction because of the electrons in the outermost orbit of the metals. We will take a rusty iron pipe, knife, test tube filled with water, and litmus paper. In an open atmosphere, the metal undergoes corrosion. We will also undergo a litmus paper test which will show whether metals are acidic or basic in nature.
Virtual tour 4: Metal reacts with Water
In this virtual tour, we will learn about the reactivity of metals. Sodium and potassium are more reactive. Thus, they react with water violently. Metals like aluminum do not react with water but they react with a vapor of water.
Virtual tour 5: Reactivity Series of Metals
The reactivity of all metals is not equal. Different metals have different reactivity. To understand this, we will perform an experiment. More reactive metals substitute less reactive metals easily, but less reactive metals cannot substitute more reactive metals.
Virtual tour 6: Properties of Ionic compounds
In this virtual tour, we will understand the properties of ionic compounds. Metals and non-metals generally react to form ionic compounds. Sodium Chloride is a solution that has high melting and boiling points. It is also a conductor of electricity.
Virtual tour 7: Magnetic separation process: Extraction of metal
There are many impurities in the air. There are many methods to remove these impurities. The magnetic separation process is used to purify over-containing impurities of iron. Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material from those that are magnetic.
Virtual tour 8: Prevention of corrosion
The outer surface of the steamers is made up of iron metal and it is directly in regular contact with water. The ocean water is highly salty and the outer surface of the steamer is in constant contact with water. There are various other methods to prevent corrosion of metal, plain method, electroplating, and producing by mixing different metals in a definite property.
Virtual tour 9: Metal Physical Properties: Sonorous, Malleability, Ductile, Lustrous, Hard
Metals produce ringing sounds when they are struck. They are ductile, which means that they can be drawn into wires. They are also lustrous, which means that they reflect light from their surface and can be polished. At last, they are malleable, which means that they can be beaten into thin sheets.
