The question asks for the term that describes the property of metals producing a ringing sound when struck. We need to identify the correct scientific term from the given options.
Correct Option: C) Sonorous — This term describes the property of materials, especially metals, to produce a characteristic ringing sound when struck. It is one of the key physical properties of metals.
The question asks to identify the correct statements about metals from the given options. We need to evaluate each statement based on the general properties of metals.
D) All the above — All the statements (i), (ii), (iii), and (iv) accurately describe the properties of metals, with appropriate exceptions noted where applicable.
The question asks to identify which of the given substances can be beaten into thin sheets. This property is known as malleability, which is characteristic of metals. We need to identify the metal among the given options.
Correct Option: A) Zinc can be beaten into thin sheets because it is a metal, and malleability is a characteristic property of metals.
The question asks to identify the property of aluminium that allows it to be formed into a foil. We need to understand the definitions of the given options and relate them to the characteristic of aluminium foil.
B) Malleability — Malleability is the property of metals that allows them to be beaten into thin sheets. Aluminium is a highly malleable metal, which is why it can be rolled into thin foils used for packaging, cooking, and other applications.
The question asks to identify a metal that is always found in a free (native) state. This relates to the reactivity series of metals. Metals that are less reactive tend to exist in their elemental form in nature, while highly reactive metals are usually found in combined states (as compounds).
Correct Option: D) Gold
The question asks to identify the correct statement regarding the ductility of metals and non-metals. Ductility is a physical property that describes a material's ability to be drawn into thin wires without breaking. We need to recall the general properties of metals and non-metals to answer this.
C) Generally, metals are ductile. This statement is correct because ductility is a characteristic property of most metals, allowing them to be drawn into wires. While there might be a few exceptions, it is a general rule.
