Stucture And Bonding Chemistry Flashcards
What happens in metallic bonding ?
Metals loose electrons to form positive ions
What’s metallic bonding between ?
Metals and metals
What’s a metallic bond ?
Delocalised electrons which are free to move that are shared
What’s ionic bonding between ?
Metal and non metal
What’s covalent bonding between ?
Non metal and non metal
What happens in ionic bonding ?
Metals lose electrons to form positive ions and the non metal gains electrons to make negative ions
How are the electrons transferred in ionic bonding ?
From metal to a non metal
What’s is an ionic bond ?
Strong electrostatic force between oppositely charged ions
How do you tell what group and ion is in ?
How many electrons are in its outer shell
What are some structure of covalent bonding ?
Diamond
Graphite
What does the dot and cross diagram display ?
Sharing of electrons
Why do metals have high boiling and melting points ?
Because they’re giant structures of atoms with strong bonds .
Why can metals be bent ?
Because they’re layers slide over each other
Why are alloys harder ?
Because they’re made up of two or more elements so the layers are distorted so cannot slide over each other
Why are metals hood conductors ?
Because theyre electrons are free to move
