2.1.1 Metals and Non-Metals Flashcards
Where are metals found in the periodic table?
To the left of the stepped line.
Where are non metals found in the periodic table?
To the right of the stepped line.
What are the physical properties of a typical metal?
Good conductor of electricity Good conductor of heat Shiny High density Malleable Ductile Sonorous
What is meant by high density?
Heavy for its size
What is meant by malleable?
Something can be hammered into a shape
What is meant by ductile?
Something that can be stretched into a wire
What is meant by sonorous?
Something that makes a ringing sound when hit
What are the properties of a typical non-metal?
Poor conductor of electricity Poor conductor of heat Dull Low density Brittle Not sonorous
What is meant by brittle?
Breaks easily
What is meant by low density?
light for its size
Which state are all metals apart from 1?
Solid (mercury is liquid)
What do we call elements that are near the stepped line on the periodic table?
Metalloids
Compare the melting points of metals and non metals.
Most metals have high melingl points
Most non metals have low melting points
What is meant by ‘chemical properties’ of an element?
How well it reacts with other elements
When a metal or non metal react with oxygen they form an…
oxide
