Bonding, structure and the properties of matter Flashcards
1
Q
metallic structures stay between two metals and form
A
electrostatic forces of attraction
2
Q
this occurs between
A
metal ions and delocalised ions
3
Q
ionic compounds
A
they stay between metals and non-metals
they loose or gain electrons that are held by strong electrostatic forces of attraction
this is done between positive and negative ions
4
Q
convelant bonding
A
They stay between two non-metals
They specify in sharing electrons and strong covalent bonds are formed
5
Q
in convelant bonding, why do they share electrons?
A
The covelant bonds become strong as they are attracted by electrostatic forces of attraction.
6
Q
what are polymers
A
long chains of repeating units
7
Q
each carbon of graphite also has
A
free electrons
8
Q
each grain of sand
A
is one giant structure of silicon and oxygen
