Final answer:
Silver, sulphur, and silicon are classified as a metal, nonmetal, and metalloid, respectively. Silver is conductive, malleable, and ductile; sulphur is non-conductive and brittle; silicon is a semi-conductive metalloid with limited malleability. Their classification directly relates to their physical and chemical properties.
Step-by-step explanation:
To compare and contrast the properties of silver, sulphur, and silicon, we must look at their physical and chemical properties. Silver is a highly conductive, malleable and ductile metal with a shiny white appearance. Sulphur is a yellow, brittle nonmetal that does not conduct heat or electricity well. Silicon, a grayish, metallic-looking metalloid, has properties intermediate between metals and nonmetals, with semi-conductive capabilities.
These elements are classified based on their properties such as conductivity, malleability, and appearance. Silver, being a metal, is known for its excellent conductivity of heat and electricity and high malleability and ductility. Sulphur, as a nonmetal, notably lacks these conductive and malleable properties. Silicon stands out as a metalloid that conducts electricity better than nonmetals but not as well as metals and exhibits limited malleability.
Classification of these elements is consolidated by their position on the periodic table, with silver classified as a metal, silicon as a metalloid, and sulphur as a nonmetal. This classification helps in predicting their reactions and uses in various applications.
