Topic 1 Metals and nonmetals Flashcards
What ions do metals form
Positive ions
Where are metals in the periodic table
The left and bottom of the table
Where are non metals in the periodic table
At the far right and the top
What ions do non metals form
Don’t generally form positive ions
What does the electron structure of an atom affect
How they will react
What makes a metal need less energy to remove the electrons and form positive ions
If they are to the far left of the periodic table they don’t have many electrons to remove
If at the bottom of the periodic table the metals outer shell is further away from the nucleus so has a weaker attraction
Why is it more difficult for non metals to form positive ions
This is because they are to the right of the table so babe lots of electrons to remove to get a full outer shell or towards the top where the outer electrons are close to the nucleus so feel strong attraction
What do non metals do instead to get a full outer shell
Share or gain electrons
What are all atoms of metals bonded by
Metallic bonding
Physical properties of metals
Strong but can bent or hammered into shapes (malleable)
Great for conducting heat and electricity
Have high boiling and melting points
Physical properties of non metals
Don’t have metallic bonding so tend to be
Dull looking
More brittle
Aren’t always solids at room temperature
Don’t generally conduct electricity
Often have a lower density
Where are transition metals found
In the center of the periodic table
What are the chemical properties of transition metals
Have the same properties of metals
Dense strong shiny
Special properties of transition metals
Can I have more than one ion
Often coloured so compounds that contain them are colourful
Often make good catalysts
