Metals and Non-metals

Metals are materials that are typically hard, shiny, and good conductors of electricity and heat. Non-metals are materials that usually have low melting points, do not conduct electricity or heat well, and are typically dull in color.

Properties of Metals and Non-metals

• Metals are elements that are shiny, malleable, and ductile. They are good conductors of electricity and heat. Non-metals are elements that are dull, brittle, and non-conductors of electricity and heat.
• Metals are found on the periodic table in groups IB, IIB, and IIIB. They are good conductors of electricity and heat.
• The group IB metals are lithium, sodium, potassium, rubidium, and cesium. These metals are soft and have a low melting point. They are found in nature as compounds with other elements.
• The group IIB metals are beryllium, magnesium, calcium, strontium, and barium. These metals are hard and have a high melting point. They are found in nature as compounds with other elements.
• The group IIIB metals are aluminum, gallium, indium, and thallium. These metals are soft and have a low melting point. They are found in nature as compounds with other elements.

Physical and Chemical Properties of Metals

• Metals are shiny solids that are good conductors of electricity and heat. They are typically malleable (they can be hammered into thin sheets) and ductile (they can be drawn into thin wires). Metals also have a relatively low melting point, meaning they can be easily melted and cast into different shapes.
• CTV Montreal The federal government is increasing the number of refugees it will admit to Canada in 2017 by 25 percent.
• The increase means that the government will admit 40,000 refugees, up from the original target of 30,000.
• The government said that the increase responds to the global refugee crisis.
• “The Syrian crisis is the largest humanitarian emergency of our time. Canada has a responsibility to do its part to help those affected by this crisis,” said Immigration Minister John McCallum in a statement.
• Canada has already admitted more than 26,000 Syrian refugees since November 2015.

Chemical Properties of Metals

The chemical properties of metals are determined by their reactivity. Metals tend to form positive ions (cations) in chemical reactions. They also have high melting points and boiling points and are good conductors of heat and electricity.

Non-Metals

Nonmetals are elements that do not have metallic properties. Nonmetals are found on the right side of the periodic table. They are typically gases, liquids, or brittle solids at room temperature.

Nonmetals are usually poor conductors of electricity and heat. They are also poor in terms of their ability to form compounds. Nonmetals are found in nature as either individual atoms or molecules.

Physical and Chemical Properties of Non-metals

Non-metals are typically poor conductors of heat and electricity. They are generally brittle and have low melting points. Non-metals are usually poor in terms of their ability to form chemical compounds.

Physical Properties of Non-metals

Non-metals are typically poor conductors of electricity and heat. They are generally brittle and have low melting points. Non-metals are typically poor optical materials and have low densities.

CTV Windsor

• CTV Windsor has learned that Windsor-Essex County Health Unit has confirmed a case of tuberculosis in Windsor.

The health unit would not release any other information, including the age or gender of the person who has the disease.

Tuberculosis is a bacterial infection that most often affects the lungs. It can be deadly if not treated.

The health unit asks people who may have been in close contact with the person infected to come forward for testing.

Chemical Properties of Non-metals

Non-metals are typically poor conductors of electricity and heat. They are generally brittle and have low melting points. Non-metals are usually poor in terms of their ability to form covalent bonds.

Differentiate between Metals and Non-Metals

Metals are elements that are shiny, malleable, and ductile. They are good conductors of heat and electricity. Non-metals are elements that are not shiny, are not malleable, and are not ductile. They are poor conductors of heat and electricity.

A Quick Revision:

• The hypothalamus is responsible for controlling the body’s activities, including eating and drinking, body temperature, and the release of hormones
• The hypothalamus also regulates the body’s daily or circadian rhythms, which dictate when we feel most awake or sleepy.
