Answer 1

Answer:

five metals - iron, uranium, sodium, aluminium, calcium five non-metals= nitrogen, oxygen,helium,sulfur, chlorine

Answer 2

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:

i) Iron

ii) Uranium

iii) Sodium

iv) Aluminum

v) Calcium

Non metals

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:

i) Nitrogen

ii) Oxygen

iii) Helium

iv) Sulfur

v) Chlorine

Uses for Metals and Non - metals

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

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

ii) 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.

iii) 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.

Non - metals are plentiful and useful. These are among the most commonly used:

i) Oxygen, a gas, is absolutely essential to human life. Not only do we breathe it and use it for medical purposes, but we also use it as an important element in combustion.

ii) Sulfur is valued for its medical properties and as an important ingredient in many chemical solutions. Sulfuric acid is an important tool for industry, used in batteries and manufacturing.

iii) Chlorine is a powerful disinfectant. It is used to purify water for drinking and fill swimming pools.
