Metals And Non Metals Flashcards
What do metals form when they react
Positive ions
What side are metals on
Left
What side are non metals on
Right
What do non metals form
Don’t form positive ions
What’s the electronic structure of a metal
Metals don’t have many electrons to remove and metals towards the bottom of the periodic table have outer electrons which are a long way from the nucleus so feel a weaker attraction
Both mean that not much energy is needed to remove the electrons so it’s likely for the elements to react to form positive ions with a full outer shell
What’s the electronic structure of non metals
Forming positive ions is difficult, as they are to the right where they have 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 a strong attraction, it easier for them to share or gain electrons to get a full outer shell
What are the physical properties of metals
They have metallic bonding
Strong, can be bent
Good at conducting heat and electricity
High boiling and melting points
What are the physical properties of non metals
They tend to have the same properties as metals,
Dull
Brittle
Don’t conduct electricity
