Coal does not have a crystalline structure, crystalline structures are only caused when and untainted sample solidifies from another state, coal is caused by pressure and heat applied over thousands of years to dead animals, as a result it contains high levels of impurities and has a very unpredictable and random structure.
the crystal structure of halite is basically a crystal structure the is made out of repeating boxes
yes
Boron's crystal structure is rhombic.
Sulphur's crystal structure is orthorhombic.
Flourine's crystal structure is cubic.
No. Coal is not a mineral for two reasons: it lacks a crystal structure and it is organic.
Both coal and graphite are made of carbon, but in different molecular structures. Diamond is also made of carbon but in a highly ordered crystal structure.
There is no crystal structure.
