C2.2.1 - Metals and Non Metals Flashcards
What is a physical property?
A characteristic that can be observed or measured
Talk about the physical properties of both metal elements and non metal elements
Metal Elements - Shiny, have high melting and boiling points, solid at room temperature, malleable and ductile when solid and good conductors
Non Metal Elements - Dull, have low melting and boiling points, half are solid while the other half are liquid at room temperature, brittle and non-ductile when solid and poor conductors
Where are metal elements placed on the periodic table?
On the left hand side
What is a chemical property?
A characteristic of a substance that can only be determined by studying its chemical reactions
Can metals react with each other?
No, they mix to form alloys
What is an alloy?
A mixture of metals
Talk about how metals and electrons interact with each other
Metals can lose electrons to make positive ions while non-metals can gain electrons to make negative ions
Can non-metals react with each other?
Yes, they create compounds
If a metal oxide dissolves in water, what happens?
They produce alkaline solutions
If a non metal oxide dissolves in water, what happens?
They produce acidic solutions
