Why are metals used to make electric wire and electronic goods?
Solution
Metals are placed at the extreme left side of the periodic table. Non-metals are placed at the extreme right side of the periodic table. Due to the ductility, malleability and conductance of electricity metals can be used to make electric wire and electronic goods.
Complete Step By Step Answer:
Chemical elements are divided into metals and nonmetals based on their character. The elements that are present at the extreme left side are known as alkali earth metals and alkaline earth metals. The elements present in these two groups were known as metals. As they contain valence electrons which can be easily lost from elements.
Metals possess some properties like ductility, malleability and conductance of electricity. Ductility is the property of making metals into thin wires. Malleability is the property of making metals into thin sheets. Due to the presence of free electrons, metals are good conductance of electricity as the free movement of free electrons leads to the good conductance of electricity.
Not only the alkali earth metals and alkaline earth metals, some d-block elements like copper, aluminum, and silver are metals that can conduct electricity. The best conductor of electricity is silver.
Due to the above properties, metals can be used for electric wires and electric goods.
Note:
Copper, aluminum, and silver are the metals that are good conductors of electricity. Generally, non-metals do not conduct electricity. The only non-metal that can conduct electricity is graphite. Due to the presence of free electrons, it can conduct electricity.
