Question

Write the list of 5 metals and nonmetals and write the properties and uses.​

Answer 1

Answer:

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

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

Answer 2

Metal are crystalline solids and Chemicals that do not have the properties of metals are Non-metals.

Explanation:

Few metals that are used in daily life are:-

1. Iron.
2. Aluminum.
3. Zinc.
4. Copper.
5. Gold.
6. Silver.

Few nonmetals that are used in daily life are:-

1. Hydrogen.
2. Helium.
3. Oxygen.
4. Carbon.
5. Sulfur.
6. Nitrogen

Uses of non-metals are as follows -

1. Oxygen is used in respiration
2. Nitrogen used in fertilizers
3. Nonmetal phosphorous is used in Plant growth
4. Iodine is used for throat infections.
5. Helium is used as inert gas for scientific experiments.

Uses of  metals are as follows:-

1. Aluminum and steel are used in utensils and household articles
2. Gold, platinum and silver are used in ornaments and jewelry
3. Aluminum is used in insulation wires.
4. Silver foil is used in foils.
5. Iron is used in automobiles.

Properties of metals:-

Ductile, malleable, good conductor of heat and electricity and lustrous.

Properties of nonmetals

Brittle, dull, poor conductor of heat and  electricity, low melting points
