above
its easy
first of all the atoms are joint by either ionic or covalent bonds
ionic bonds are more rigid and hard than covalent bond
the atoms are connected in a network in either 2-d or 3-d way
if the distance between atoms are small and if the are joint by ionic bond they will have a crystalline structure
