HideShow resource information
descrive crystal lattice structire
chlorine is surrounded by 6 Na, with co-ordination bond of 6, Na is surrounded by 6 Cl and has a co-orination bond of 6, ratio 6:6
1 of 8
what is the cruysral lattice called
face centre cubic
2 of 8
descrive casuium chlorine
Cl is surrounded by 8 Cs atoms and has a coordination of 8, Cs is surrounded by 8 chlorine and has a coridantion od 8 and the ration os 8:8
3 of 8
what os the caesium chloride called
body centre cubic
4 of 8
differences between nacl and cscl
cscl has to accomidtae more atoms, it has more elctrostaic force between ions, ionuc bonding is stronger
5 of 8
