Structure And Bonding Flashcards
What happens during ionic bonding
Electrons are transferred and ions are formed
What happens during covalent bonding
Electrons are shared and no ions are formed
What makes an atom stable
A Full outer shell
Why are the noble gasses (elements in group 0) really unreactive
They have full outer shells
What happens if atoms don’t have a full outer shell
React with another atoms
What is an ion
An atom that has lost or gained electrons
Where on the periodic table can metals be found
Left
In terms of their electronic structure, why are the metals found here
They don’t have many electrons in their outer shell
Do metals form positive or negative ions
Positive
What type of bonding is between metal and non metals
Ionic
What force holds opposite charges together
Strong electrostatic forces
Why do ionic compounds have high melting points (2 answers)
Because they have strong electrostatic forces which take a lot of energy to overcome
Why can’t ionic compounds conduct electricity when solids
The ions cannot move
When can ionic compounds conduct electricity
In a solution (dissolved)
When melted (“molten”)
Why can ionic compounds conduct electricity when molten (melted)
The ions can flow freely
