Answer

Good conductor of electricity, malleable , sonorous,  ductility, high melting point except gallium  and caesium

Answer

Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days). ... Ductility: Metals can be drawn into wires.

Answer

They lustrous, malleable,conductors of heat and electricity, ductile, sonorous,have high density..

Answer

The properties are :-

1)metallic lustre :- it have a shining surface.

2)strength :- it have a high tensile strength.

3)melting and boiling point :- like eg. sodium(Na) and potassium (K) have a high melting and boiling point.

4) malleability and ductility :- it can be drawn into thin wires called ductile. and can be beaten into thin sheets with a hammer called malleability.

5) density :- all metals have a density but... sodium and potassium don't have density

Answer

Metal Physical Properties:

Lustrous (shiny)

Good conductors of heat and electricity.

High melting point.

High density (heavy for their size)

Malleable (can be hammered)

Ductile (can be drawn into wires)

Usually solid at room temperature (an exception is mercury)

Opaque as a thin sheet (can't see through metals

Answer

Physical Properties of Metals

Metals are a group of elements characterized by their ability to conduct electricity and heat, as well as their shiny appearance, malleability, and ductility. They have a wide range of physical properties that distinguish them from other elements. Let's explore these properties in detail:

1. Electrical Conductivity:
Metals are excellent conductors of electricity. This is due to their delocalized electrons, which are free to move throughout the metal lattice. When a voltage is applied, these electrons flow easily, allowing the metal to conduct electric current.

2. Thermal Conductivity:
Similar to electrical conductivity, metals also possess high thermal conductivity. This means that they are efficient in transferring heat. The delocalized electrons play a crucial role in this property by rapidly transferring thermal energy through the metal lattice.

3. Malleability:
One of the unique properties of metals is their malleability, which refers to their ability to be hammered or rolled into thin sheets without breaking. This property is due to the metallic bonding, which allows the layers of metal atoms to slide over each other without separating.

4. Ductility:
Metals are also highly ductile, meaning they can be drawn into thin wires without breaking. The metallic bonding enables the atoms to stretch and rearrange themselves without disrupting the overall structure of the metal.

5. Luster:
Metals possess a characteristic luster or shine. This is because of their ability to reflect light due to the presence of free electrons. As light strikes the metal surface, the free electrons oscillate and re-emit the light, giving metals their shiny appearance.

6. High Density:
Most metals have high densities, meaning they are heavy compared to their volume. This property is a result of the close packing of metal atoms within the lattice structure.

7. High Melting and Boiling Points:
Metals generally have high melting and boiling points compared to nonmetals. The strong metallic bonds between atoms require a significant amount of energy to break and transition from solid to liquid or gas states.

8. Solid State at Room Temperature:
The majority of metals are solid at room temperature, except for a few, such as mercury. This solid state is due to the strong metallic bonding, which holds the metal atoms together in a rigid structure.

In conclusion, metals possess several distinctive physical properties that make them unique. These properties include their excellent electrical and thermal conductivity, malleability, ductility, luster, high density, high melting and boiling points, and solid state at room temperature. Understanding these properties is crucial in various fields, including materials science, engineering, and everyday applications.
