Hint: Metals are substances that we see in our daily lives, such as keys, chains, and jewellery. They have qualities that are distinct from non-metals. Metals come in a variety of forms in nature and are frequently employed by humans in their daily lives. Iron, aluminium, copper, zinc, mercury, sodium, and lead are just a few examples.
Complete answer:
1) Malleability : Malleability is the property of a metal that allows it to be drawn into sheets. It changes with the temperature. This feature can be found in metals such as gold, silver, copper, iron, and others. This property of malleability is not present in all metals.
2) Ductility : The ability to be drawn into wire is known as ductility. It is a persistent strain that occurs as a result of a tension test fracture. It's an advantageous quality for machine components that are subjected to unexpected overloads or impact loads. Metals' ductility reduces as their temperature rises because metals weaken as their temperature rises.
3) Metallic bonding: The force that holds the atoms of a metal together is known as the metallic bond. Metals are made up of positively charged ions that are bound in a crystal lattice and negatively charged electrons that move freely across it. The cohesive force that holds metal atoms together and forms a metallic bond is provided by free electrons. A metallic bond is formed when the electrostatic forces of attraction between electrons and the positive nuclei of metal atoms combine to form a bond.
4) Bond polarity: Bond polarity is the separation of electric charge along a bond, resulting in an electric dipole or dipole moment in a molecule or its chemical groups. The term "polar compound" refers to a chemical species that consists of two or more atoms held together by covalent bonds that are polar in nature due to unequal electron sharing.
Note:
Metals have a high density and are dazzling and lustrous. 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.
