Discovering the secrets of the elements

The Power of Metals

• Metals are a group of elements known for their high electrical and thermal conductivity (ability pass through something).

• They are malleable (able to be hammered or pressed permanently out of shape without breaking or cracking.) and ductile (able to be drawn out into a thin wire.*), allowing them to be shaped into various forms.

• Metals play a crucial role in industries such as construction, transportation, and electronics.

• Common examples of metals include iron, aluminum, and copper.

• 3 types of metals

​Reactive Metal

​

Rare Earth

Transition metals

The Non-Metals

• Definition: Non-metals are elements that lack metallic properties.
• Characteristics: They are poor conductors of heat and electricity, brittle, and have low melting and boiling points.
• Examples: Oxygen (O), Nitrogen (N), Carbon (C), and Sulfur (S).
• Importance: Non-metals play crucial roles in various biological, environmental, and industrial processes.

​Non - Metals

Oxygen - The Vital Non-Metal

Oxygen is a non-metal that is essential for life on Earth. It makes up about 21% of the Earth's atmosphere and is crucial for respiration. Without oxygen, combustion and many chemical reactions would not be possible. It is also used in medical treatments and industrial processes. Oxygen is a true lifesaver!

The Metalloids

• Metalloids are elements that have properties of both metals and nonmetals.

• They are located on the staircase of the periodic table.

• Common metalloids include boron, silicon, and germanium.

• They have intermediate electrical conductivity and can be semiconductors.

• Metalloids are used in electronics, optics, and ceramics.
