Answer:

hey mate here is your answer

Explanation:

Five Metals

Metals are usually hard, dense conductors, often exhibiting a shiny luster. Metallic elements readily lose electrons to form positive ions. Except for mercury, metals are solids at room temperature and pressure. Examples include:

Iron

Uranium

Sodium

Aluminum

Calcium

Five Nonmetals

The nonmetals are on the upper right-hand side of the periodic table. Nonmetals are typically poor electrical and thermal conductors and don't have a metallic luster. They can be found as solids, liquids, or gases under ordinary conditions. Examples include:

Nitrogen

Oxygen

Helium

Sulfur

Chlorine

Uses for Metals and Nonmetals

A metal's use is directly linked to its qualities. For example:

Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.

Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks.

Some metals have specific qualities that dictate their use. For example, copper is a good choice for wiring because it is particularly good at conducting electricity. Tungsten is used for the filaments of light bulbs because it glows white-hot without melting.

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)

Correct Answer:

Here are the 5 metals and non metals with their physical properties and uses:
