Thats more like metallic bonding....
IS BORON a semi metal ??
WHERE is NID ???

add small holes between metallic bonding to make it look like a alloy..
(like u see small black circles in my diag)
no boron is a non-metal..
i dont know where is nid..
answeered all ur questions :D :D :D
Saladin:
actually it will have more of a diamond like structure.

Because Carbon and Silicon have the same bonding abilities.
Combining carbon and silicon will fore somewhat of a semi conductor. U dont need to show free electrons because there arent any.
Secondly, in semi conductors, the electrostatic force between te nucleus and the electrons are weak, and therefore, you have to go to A level stuff to explain.
The main thing they are trying to see, if u can identify that if it is tetrahedral in structure.
I hope that answers ur q.
SGVaibhav:
is that diagram for an alloy?? or boron??
wow im back to chemistry after months and it feel good xD ;D

HOLD YOUR HORSES PEOPLE !!!
Everyone is getting confused with what I am asking.... so ill put it here in short:
1.) An alloy is a mixture 2 or more metals. In a diagram for an ALLOY how would you show the mobile electrons ??
2.) Is boron a metal or metalloid ? WHat is its charge ?
