Study Notes
Metals and Non-Metals
- Elements are classified as metals or non-metals based on their properties.
- Consider how metals and non-metals are used in daily life.
- Think about the properties that distinguish metals from non-metals.
- Explore how these properties relate to the uses of different elements.
Physical Properties of Metals
- Metals are often shiny (lustrous).
- Metals can be hammered into thin sheets (malleable).
- Metals can be drawn into wires (ductile).
- Metals conduct heat and electricity well.
- Metals are generally solids at room temperature (except for mercury).
- They have high melting and boiling points in most cases.
- Some metals, like sodium, react with water.
- Metals have a lustrous (shiny) surface. This property is called metallic lustre.
- Metals can be grouped by comparing their physical properties.
- Metals are good conductors of heat.
- Silver and copper are the best heat conductors.
- Lead and mercury are poor heat conductors.
- Metals can be beaten into thin sheets, a property known as malleability.
- Gold, in particular, is highly malleable.
- The ability of a metal to be drawn into wires is known as ductility.
- Gold also exhibits high ductility.
- Metals, in their pure state, often have a shining surface.
- Some metals can be cut with a knife (e.g., sodium).
- Metals can be hard, with the degree of hardness varying from metal to metal.
- Gallium and caesium are soft metals with exceptionally low melting points.
- Some metals exist as liquids at room temperature (e.g., mercury).
- Metals react with oxygen to form metal oxides. Different metals react with oxygen at different rates, which influences the properties and appearance of the metal.
- Some metals burn readily in air, while others do not.
- Some metals react vigorously when exposed to water or steam, others do not.
- Different metals exhibit varying degrees of reactivity with different substances.
- Metals react differently with different acids. Some metals do not react with dilute hydrochloric acid, while others do. Some metals react more vigorously with concentrated nitric acid than with dilute nitric acid.
- Metals can be used for making cooking vessels because of their properties.
- Metals are good conductors of electricity.
Activities
- Rub samples of various metals (iron, copper, aluminum, magnesium) against sandpaper to observe metallic lustre.
- Clean the surface of each metal sample.
- Note the appearance of each sample before and after rubbing them with sandpaper.
- Cut different metals (iron, copper, aluminum, magnesium) with a knife to observe their malleability and ductility. Handle sodium metal carefully in accordance with safety procedures.
- Observe the appearance of sodium metal and how it reacts with air or a watch glass with a knife.
- Conduct experiments to determine how well metals conduct heat, considering aspects like conductors of heat, and how they conduct electricity.
- Take samples of iron, zinc, lead, and copper, to observe their hardness by striking them with a hammer.
- Record shape changes.
- Identify metals whose wires are commonly seen in daily life.
- Investigate the ductility of metals by drawing a wire from a small amount of gold (showing the ability to be drawn into thin wires).
- Investigate how metals are used in making cooking vessels.
- Observe if metals conduct electricity.
- Note that metals are generally hard, with the degree of hardness varying from metal to metal.
- Test metal samples for reactivity with different substances/conditions.
- Conduct experiments to observe how metals react with hard surfaces. Record the changes in the shape of the metals.
- Observe the changes in the shape of metals like iron, zinc, lead, and copper when hammered (observing malleability and ductility).
- Perform activities to observe how different metals conduct electricity, noting the differences.
- Investigate the properties of metals by observing how they react when struck with a hammer (observing malleability and ductility).
- Use different metals (iron, zinc, lead and copper), to create electric circuits, observing if the bulb glows in each case, to determine conductivity.
- Observe how different metals react with dilute acids.
- Perform experiments to observe how metals react with steam.
- Note that some metals have very low melting points (e.g., gallium and cesium).
- Observe differences in the hardness of various metals.
- Note that some metals exhibit a shining surface (metallic lustre) when exposed to air.
- Not all metals react with oxygen, water, or acids in the same way.
- Different metals react differently to various conditions, such as heat and air.
- Some metals can be cut with a knife (malleable).
- Metals have a variety of hardness.
- Some metals, such as potassium and sodium, are so reactive that they should be stored in kerosene.
- Metals react with water to form metal hydroxides and hydrogen gas.
- Some metal oxides can be acidic or basic.
- Metals react with oxygen to form metal oxides. Different metals react differently to air at different temperatures. Different metals react with steam at different temperatures.
- Some metals react with dilute acids, forming salts and hydrogen gas.
- Some metals, like gallium and cesium, have very low melting points.
- Iodine is a non-metal that can exist in different forms (allotopes).
- Carbon is a non-metal that can exist as diamond and graphite.
- Alkali metals (e.g., lithium, sodium, and potassium) are soft enough to cut with a knife.
