Question

Write three general physical properties of metal.

Answer 1

An element, compound, or alloy that is a good conductor of both electricity and heat is referred to as a metal. Gold, sodium, copper, iron, and a variety of other metals are examples. The majority of metals are malleable, ductile, and lustrous.

Complete answer:
The following are three general physical features of metals:
Density of Metals: - Metals have a high density and are gleaming and brilliant. Because metallic bonding is exceptionally strong, the atoms are hesitant to break apart into a liquid or gas, they have very high melting and boiling temperatures.
Conductivity of Metals: - Metals are conductive in general, having high electrical conductivity and thermal conductivity. They are often pliable and ductile, deforming without cleaving under stress. Hitting a metal with a hammer, for example, will “dent” the metal rather than break it into pieces.
Malleability: - The capacity of metals to be hammered, crushed, or rolled into thin sheets without breaking is referred to as malleability. In other words, a metal's ability to deform and take on a new shape when compressed. The amount of pressure (compressive stress) a metal can endure without breaking is a measure of its malleability. Various metals have different crystal structures, which causes differences in malleability.

Note:
Metals, it should be emphasised, play a critical function in human life. Their absence may result in a variety of illnesses in the human body. Metals have also been used to develop therapeutically helpful medications for a variety of ailments, including cancer, arthritis, ulcers, and others. The catalytic reaction of enzymes is greatly aided by metals present in them.
